You can use the \framed command.

\define[2]\ChoiceOne

{\dontleavehmode\framed[frame=off,location=bottom,align=middle,offset=0pt]{#1\\#2}}

\defineframed[ChoiceTwo][frame=off,location=bottom,align=middle,offset=0pt]

\starttext

(\ChoiceOne{x}{One}~* \ChoiceOne{1}{Two}~* \ChoiceOne{x}{Three}~* 
\ChoiceOne{2}{Four}) is even.

(\ChoiceTwo{x\\One}~* \ChoiceTwo{1\\Two}~* \ChoiceTwo{x\\Three}~* 
\ChoiceTwo{2\\Four}) is even.

\stoptext

Wolfgang
