B. Statement-1 is True, Statement-2 is True , Statement-2 is not a correct explanation for Statement-1
C. Statement- 1 is True, Statement-2 is False
D. Statement-1 is False, Statement -2 is True

Explanation

To solve the question, we will analyze both statements regarding the sulphonation of toluene.

### Step-by-Step Solution:

1. **Understanding Toluene and Sulphonation**:
- Toluene (C6H5CH3) is an aromatic hydrocarbon that contains a methyl group (-CH3) attached to a benzene ring.
- Sulphonation is the process of introducing a sulfonyl group (-SO3H) into an organic compound, typically through the reaction of the compound with sulfuric acid or sulfur trioxide.

2. **Determining the Product of Toluene Sulphonation**:
- When toluene undergoes sulphonation, the sulfonyl group can attach to the benzene ring at different positions: ortho (adjacent to the methyl group), meta (one carbon away), or para (opposite to the methyl group).
- The methyl group is an activating group and directs electrophilic substitution to the ortho and para positions. Therefore, the sulfonation of toluene primarily yields ortho- and para-toluenesulfonic acids.

3. **Evaluating Statement-1**:
- Statement-1 claims that toluene on sulphonation gives m-toluenesulfonic acid.
- This statement is **false** because the major products are ortho- and para-toluenesulfonic acids, not meta-toluenesulfonic acid.

4. **Evaluating Statement-2**:
- Statement-2 states that sulphonation is a reversible reaction.
- This statement is **true** because the sulfonic acid group can be removed under certain conditions, making the reaction reversible.

5. **Conclusion**:
- Statement-1 is false, and Statement-2 is true.

### Final Answer:
- Statement-1: False
- Statement-2: True
