Section of most attractive figure (4)
I believe the answer is:
stat
'figure' is the definition.
(statistic)
'section of most attractive' is the wordplay.
'section of' indicates a hidden word.
'STAT' can be found hidden inside 'most attractive'.
(Other definitions for stat that I've seen before include "Photocopy" , "accepted numerical fact" , "figure used in estimates" , "Might it control warmth" , "Doctor's immediately" .)
