The correct option is A 1,2,4
1. $[H e] 2 s^{1}$ is electronic configuration of Li which belong to group 1.
2. $[H e] 3 s^{2}$ is electronic configuration of Be which belong to group 2.
3. $[H e] 2 s^{2} 2 p^{2}$ is electronic configuration of C which belong to group 14.
4. $[N e] 3 s^{2} 3 p^{1}$ is electronic configuration of Al which belong to group 13.
Hence correct option is a.
