Answer 1

Answer: (A), (D)

The correct options are
A al
D amine

'al' is a secondary suffix for the aldehyde functional group ($-CHO$).
'amine' is the secondary suffix for amines ($-N{H}_2$).

'oxo' and 'amino' are prefixes used for ketone and amine group in presence of a functional group with higher priority.
