Record in award is challenged (4)
I believe the answer is:
disc
'record' is the definition.
(eg a CD, compact disc)
'in award is challenged' is the wordplay.
'in' says the answer is hidden in the clue.
'DISC' is hidden within 'award is challenged'.
(Other definitions for disc that I've seen before include "Flat, circular plate - record" , "Sound recording" , "45, eg?" , "Thin circular plate, as in CD" , "CD perhaps" .)
