I believe the answer is:
option
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">right to choose</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this before)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Other definitions for option that I've seen before include "Something choosable" , "Something that may be chosen" , "Preference" , "Potion (anag.)" , "Freedom to choose" .)
