Choice, preference (6)
I believe the answer is:
option
I believe this clue is a double definition.
'choice' is the first definition.
(I know that choice can be written as option)
'preference' is the second definition.
(I've seen this before)
(Other definitions for option that I've seen before include "Choice of portion" , "Something choosable" , "Right to choose" , "Preference" , "Alternative for choice" .)
