Solution
The correct option is
D
I, II and III
Carbocations are positive charge species with incomplete octets so they are electrophiles.
Free radicals have one unpaired electron so they are paramagnetic in nature.
Carbene has an incomplete octet of carbon but carbanion has a complete octet of carbon.
Hence, the correct option is D.
