preference

I'm a little stuck... Click here to teach me more about this clue!

'a choice?' is the definition.
(I know that preference is a type of alternative)

I can't explain the rest of the clue.

(Other definitions for preference that I've seen before include "favourite" , "Choice (of A rather than B)" , "Partiality" , "First choice" , "Fancy" .)

I've seen this clue in the Evening Standard.
