Options[f]={"a"->Red}
(* {a -> Red} *)

f[Name][x_,options:OptionsPattern[]] :=
  Block[{},
    Plot[x, {x,0,10}, PlotStyle -> OptionValue[f,"a"]];
    OptionValue[f, "a"]
  ]

f[Name][x,"a"->Black]

The OptionValue of is always Red

Sols：

Options[f]={"a"->Red}; 
f[Name][x_,opts:OptionsPattern[f]]:=Plot[x,{x,0,10},PlotStyl‌e->OptionValue[f,{op‌ts},"a"]] 
f[Name][x,"a"->Black]

The issue is that you attach your option to f but use a SubValue of f. – Sascha Sep 15 '16 at 08:15

@Sascha thanks, solved Options[f]={"a"->Red}; f[Name][x_,opts:OptionsPattern[f]]:=Plot[x,{x,0,10},PlotStyle->OptionValue[f,{opts},"a"]] f[Name][x,"a"->Black] – HyperGroups Sep 15 '16 at 08:32
