Option, alternative (6)
I believe the answer is:
choice
I believe this clue is a double definition.
'option' is the first definition.
(I know that option can be written as choice)
'alternative' is the second definition.
(I know that alternative can be written as choice)
(Other definitions for choice that I've seen before include "Possibility" , "Volition" , "Very good" , "of superior quality" , "Act or power of selecting" .)
