Make options al horizontal instead vertical in multiple choice

Question

I want to type some multiple choice questions. I have the following code. The problem is that in some questions I need options in one line and evenly spaced, and in some questions I need two in one line and evenly spaced. How can I do that. I know that there are some answers related to this but I tried to figure out from that how to change this code, but every time I get an error and I don't want to use a different code all together. It will be nice if I am able to do this in this very code.

Thanks for the help in advance.

Sorry, i cannot use my phone as well at night as i do at day time. What i meant to link was this which especially mentions tasks (as Carla did above). There even is an image of the example-output. — Johannes_B, Oct 28 '18 at 07:56

From this question: we create a multicolumn environment:

\makeatletter
\newenvironment{multichoices}[1][2]{%
\begin{multicols}{#1}}{%
\end{multicols}}
\makeatother

and use it in the choices environment. MWE:

\documentclass{article}
\usepackage{multicol}
%--------------------------------------------------------------------
%--------------------------------------------------------------------
\newcounter{choice}
\renewcommand\thechoice{($\alph{choice}$)}
\newcommand\choicelabel{\thechoice}
%--------------------------------------------------------------------------------
\newenvironment{choices}%
  {\list{\choicelabel}%
     {\usecounter{choice}\def\makelabel##1{\hss\llap{##1}}%
       \settowidth{\leftmargin}{W.\hskip\labelsep\hskip 0 em}%
       \def\choice{%
         \item
       } % choice
       \labelwidth\leftmargin\advance\labelwidth-\labelsep
       \topsep=0pt
       \partopsep=0pt
     }%
  }%
  {\endlist}
%--------------------------------------------------------------------------------
\def\CChoice{%
      \choice
      \addanswer{\theenumi}{\thechoice}%
    }
    \let\CChoice\CChoice
%    \par % Uncomment this to have choices always start a new line
   % \let\par\@empty
    % If we're continuing the paragraph containing the question,
    % then leave a bit of space before the first choice:
    \ifvmode\else\enskip\fi
    \ignorespaces
  %
  {}
\makeatother
\newbox\allanswers
\setbox\allanswers=\hbox{}
\newcommand{\addanswer}[2]{%
  \global\setbox\allanswers=\hbox{\unhbox\allanswers \quad #1.~#2}%
}
\newcommand{\showanswers}{%
  \vfill
  \begin{center}
    Answers
  \end{center}
  \unhbox\allanswers
}

\makeatletter
\newenvironment{multichoices}[1][2]{%
\begin{multicols}{#1}}{%
\end{multicols}}
\makeatother

%--------------------------------------------------------------------
\begin{document}

\begin{enumerate}
\item One of these things is not like the others; one of these things
  is not the same.  Which one doesn't belong?
  \begin{choices}
   \begin{multichoices}[4]
    \choice George
    \choice Paul
    \choice John
    \CChoice Ringo
   \end{multichoices}
  \end{choices}
\item What was the color of George Washinton's white horse?
  \begin{choices}
   \begin{multichoices}[2]
    \choice Green
    \CChoice Yellow
    \choice White
    \choice Socrates    
   \end{multichoices}
  \end{choices}
\end{enumerate}
\end{document}

BTW: why not use the exam class?

Thanks for the help. Its part of a bigger project and the document class is book so I can add another class. — Kumarm, Oct 29 '18 at 21:08
