As we have learnt,

Nitrogen owing to its small size has a tendency to form \mathrm{p\pi - p\pi} multiple bonds with itself but fails to form tetramer because of its small size. The \mathrm{N -N} single bond is weak due to lone pair - lone pair repulsions and hence, it does not show catenation property.

P, Sb and As have tendency of forming tetramer as they have larger size.

Therefore, option (4) is correct.
