How to create circle checkbox multiple choice exam with choice letters inside circle

Question

I can't find any place where I can get an exam environment where I can make a multiple choice exam with circle checkbox where the options are in letters A,B,C,D and E, and these are inside the checkboxes. Please help...

Using some Tikz trickery it can be done. If you are using oneparcheckboxes, all you have to do is modify the \checkboxchar and \checkedchar commands:

% Make checkbox character a circle with the letter
\checkboxchar{\tikz[baseline={([yshift=-.8ex]current bounding box.center)}]\node[shape=circle,minimum size=8mm,draw] at (0,0) {\thechoice};}
% Make checked box character bold WITH surd
%\checkedchar{\tikz[baseline={([yshift=-.8ex]current bounding box.center)}]\node[shape=circle,minimum size=8mm,draw] at (0,0) {} node at (0,0) {\thechoice\llap{$\surd$}};}
% Make checked box character bold
\checkedchar{\tikz[baseline={([yshift=-.8ex]current bounding box.center)}]\node[shape=circle,minimum size=8mm,draw] at (0,0) {} node at (0,0) {\thechoice};}

But this will not work for the checkboxes environment because it does not keep track of the items using a counter. For that, you have to modify the environment:

\makeatletter
    \renewenvironment{checkboxes}%
       {\setcounter{choice}{0}\list{\checkbox@char}%
          {%
            \settowidth{\leftmargin}{W.\hskip\labelsep\hskip 2.5em}%
            \def\choice{%
              \if@correctchoice
                \color@endgroup \endgroup
              \fi
              \stepcounter{choice}
              \item[\checked@char]
              \do@choice@pageinfo
            } % choice
            \def\CorrectChoice{%
              \if@correctchoice
                \color@endgroup \endgroup
              \fi
              \ifprintanswers
                % We can't say \choice here, because that would
                % insert an \endgroup.
                % 2016/05/10: We say \color@begingroup in addition to
                % \begingroup in case \CorrectChoiceEmphasis involves color
                % and the text exactly fills the line (which would
                % otherwise create a blank line after this choice):
                % 2016/05/11: We leave hmode if we're in it,
                % i.e., if there's no blank line preceding this
                % \CorrectChoice command.  (Without this, the
                % \special created by a \color{whatever} command that might
                % be inserted by \CorrectChoice@Emphasis would be appended 
                % to the previous \choice, which could cause an extra
                % (blank) line to be inserted before this \CorrectChoice.)
                % Since \par and \endgraf seem to cancel \@totalleftmargin
                % (for reasons I don't understand), we'll do the following:
                % Motivated by  the def of \leavevmode, 
                %      \def\leavevmode{\unhbox\voidb@x}
                % we will now leave hmode (if we're in hmode):
                \ifhmode \unskip\unskip\unvbox\voidb@x \fi
                \begingroup \color@begingroup \@correctchoicetrue
                \CorrectChoice@Emphasis
                \stepcounter{choice}
                \item[\checked@char]
              \else
                \stepcounter{choice}
                \item[\checked@char]
              \fi
              \do@choice@pageinfo
            } % CorrectChoice
            \let\correctchoice\CorrectChoice
            \labelwidth\leftmargin\advance\labelwidth-\labelsep
            \topsep=0pt
            \partopsep=0pt
            \checkboxeshook
          }%
       }%
       {\if@correctchoice \color@endgroup \endgroup \fi \endlist}
     \makeatother

And now for a MWE:

\documentclass[a4paper,12pt,answers]{exam}
\usepackage{tikz}
\makeatletter
\renewenvironment{checkboxes}%
   {\setcounter{choice}{0}\list{\checkbox@char}%
      {%

        \def\choice{%
          \if@correctchoice
            \color@endgroup \endgroup
          \fi
          \stepcounter{choice}
          \item[\checked@char]
          \do@choice@pageinfo
        } % choice
        \def\CorrectChoice{%
          \if@correctchoice
            \color@endgroup \endgroup
          \fi
          \ifprintanswers
            % We can't say \choice here, because that would
            % insert an \endgroup.
            % 2016/05/10: We say \color@begingroup in addition to

            % \special created by a \color{whatever} command that might

            \begingroup \color@begingroup @correctchoicetrue

            \stepcounter{choice}
            \item[\checked@char]
          \else
            \stepcounter{choice}
            \item[\checked@char]
          \fi
