She gives you the option (4)
I believe the answer is:
else
'she' is the definition.
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for else that I've seen before include "In addition; different" , "Otherwise; different from" , "Besides, otherwise" , "Adverb meaning if not, otherwise" , "Eels (anag)" .)
