Ring section from multiple choice (4)
I believe the answer is:
echo
'ring' is the definition.
('echo' can be a synonym of 'ring')
'section from multiple choice' is the wordplay.
'section' indicates the answer is hidden within the clue.
'ECHO' can be found hidden inside 'from multiple choice'.
(Other definitions for echo that I've seen before include "Reproduction" , "Reflection of sound wave" , "Noise heard again" , "ring" , "letter we hear" .)
