Answer 1

Answer:

option (3) is correct

Explanation:

electronic configuration of Al:

1s²2s²2p⁶3s²3p¹

On releasing one electron, it will attain a stable electronic configuration.

Hence, it has lowest IP, comparing others configuration (except Na, since it attains configuration of Ne, an inert gas and hence is more stable than Al, and hence has more lower IP value).

Hope it helps.
