Selection, option (6)
I believe the answer is:
choice
I believe this clue is a double definition.
'selection' is the first definition.
(I know that selection can be written as choice)
'option' is the second definition.
(I know that option can be written as choice)
(Other definitions for choice that I've seen before include "Plum" , "Sophie's ---, William Styron novel" , "'Option, alternative (6)'" , "Select" , "Act of selection" .)
