Chooses to stop out (4)
I believe the answer is:
'chooses' is the definition.
(I've seen this before)
'stop out' is the wordplay.
'out' indicates anagramming the letters (out can mean wrong or inaccurate).
'stop' with letters rearranged gives 'OPTS'.
'to' is the link.
(Other definitions for opts that I've seen before include "Makes choice from post" , "Elects" , "Chooses from a range of possibilities" , "Selects between alternatives" , "Picks needed" .)
