Rounded — opt (for) (5)
I believe the answer is:
plump
I believe this is a double definition.
'rounded' is the first definition.
(I've seen this before)
'opt for' is the second definition.
(I've seen this before)
(Other definitions for plump that I've seen before include "Chubby, rounded" , "stout" , "Having a full rounded shape" , "Slightly fat" , "Not obese, just pleasantly rounded" .)
