The correct option is (c) phosphorus and sulphur catenate due to the existence of d-orbitals and form strainless structures.
Explanation:
As nitrogen and oxygen atoms are small and highly electronegative with no vacant d-orbitals available for bonding thus, multiple bonds are formed between oxygen-oxygen and nitrogen-nitrogen atoms.
N=N O=O
As the size of P and S atoms is large so multiple bonds are not strong enough, also catenation is possible due to vacant d-orbitals.
