Select the correct option based on statements below:
Assertion (A): Both rhombic and monoclinic sulphur exist as S8 but oxygen exists as O2.
Reason (R): Oxygen forms  pπ   -   pπ multiple bonds due to its small size and small bond length but  pπ   -   pπ bonding is not possible in sulphur.
    
1. Both (A) and (R) are True and (R) is the correct explanation of (A).
2. Both (A) and (R) are True but (R) is not the correct explanation of (A).
3. (A) is True but (R) is False.
4. Both (A) and (R) are False.
HINT: Oxygen can form π bonds due to its small size but sulphur cannot form.
Explanation:
Both rhombic and monoclinic sulphur exists as S8 but oxygen exists as O2, because oxygen forms  -  multiple bonds
due to it's small size and small bond length.
But  -  bonding is not possible in sulphur due to its bigger size as compared to oxygen.
The structures of Sand O2 are as follows:
