There's nothing to point out - there's a choice (6)
I believe the answer is:
option
'there's a choice' is the definition.
(synonyms)
'there's nothing to point out' is the wordplay.
'there's nothing' becomes 'o' (I've seen this in other clues).
'to' says to put letters next to each other.
'out' is an anagram indicator (out can mean wrong or inaccurate).
'point' with letters rearranged gives 'ption'.
'o'+'ption'='OPTION'
(Other definitions for option that I've seen before include "Something that may be chosen" , "Alternative for choice" , "Preference" , "Choice, selection" , "Potion (anag.)" .)
