Reaction:

The basicity order will depend on the groups attached with 'N' other than the benzene ring.

In (III) −C2?H5? increases the basicity order due to its +I effect.

Therefore (III) has the highest basicity,

(II) has lowest basicity due to the -I effect of −COCH3? group.

Hence the correct order is (III)>(I)>(II).

Therefore, Option(1) is correct
