Assertion (A) Both rhombic and monoclinic sulphur exist as `S_(8)` but oxygen exists as `O_(2)`.
Reason (R ) Oxygen forms `ppi-ppi` multiple bond due to small size and small bond length but `ppi-ppi` bonding is not possoble is not possible in sulphur.

Options

A. Both Assertion and Reason are correct statements , and Reason is the correct explation of the Assertion.
B. Both Assertion and Reason are correct statements , and Reason is not the correct explanation of the Assertion.
C. Assertion is correct, but Reason is wrong statement.
D. Assertion is wrong but Reason is correct statement.

Explanation

To analyze the given assertion and reason, we can break down the problem step by step.

### Step 1: Understand the Assertion
The assertion states that both rhombic and monoclinic sulfur exist as \( S_8 \), while oxygen exists as \( O_2 \).

- **Rhombic and Monoclinic Sulfur**: Sulfur can crystallize in different forms, namely rhombic and monoclinic, both of which are composed of \( S_8 \) molecules. This is a well-established fact in chemistry.
- **Oxygen**: Oxygen exists as a diatomic molecule \( O_2 \), which is also a known fact.
