B. Statement -1 and Statement- 2 both are False.
C. Statement -1 is true, Statement- 2 is false.
D. Statement -1 is true, Statement- 2 is false.

Answer

To solve the question, we need to analyze both statements regarding the preparation of sodium thiosulphate (Na₂S₂O₃) and the reactions involved.

### Step-by-Step Solution:

**Step 1: Understanding Statement 1**
- Statement 1 claims that sodium thiosulphate (Na₂S₂O₃) is not prepared by boiling sodium sulfite (Na₂SO₃) with sulfur (S) in an acidic medium.
- This implies that the reaction between Na₂SO₃ and S in the presence of an acid does not yield Na₂S₂O₃.

**Hint for Step 1:** Consider the nature of the reactants and the expected products when mixed in an acidic medium.

**Step 2: Analyzing Statement 2**
- Statement 2 provides a reaction: Na₂SO₃ + H⁺ → 2Na⁺ + H₂SO₃ + S.
- This indicates that when sodium sulfite reacts with hydrogen ions (from the acidic medium), it decomposes into sodium ions, sulfurous acid (H₂SO₃), and sulfur (S).

**Hint for Step 2:** Look at how the presence of H⁺ ions affects the decomposition of sodium sulfite.

**Step 3: Evaluating the Reaction**
- The reaction suggests that instead of forming sodium thiosulphate, the sodium sulfite decomposes to produce sulfur and sulfurous acid.
- Therefore, the presence of H⁺ ions prevents the formation of sodium thiosulphate.

**Hint for Step 3:** Think about how acidic conditions can influence the stability and formation of different chemical species.

**Step 4: Conclusion on Statements**
- Since the reaction in Statement 2 shows that Na₂SO₃ does not yield Na₂S₂O₃ in acidic conditions, Statement 1 is true.
- Statement 2 is also true as it correctly describes the reaction that occurs.
- Additionally, Statement 2 serves as a correct explanation for Statement 1.

**Hint for Step 4:** Confirm if both statements are logically connected and if one explains the other.

### Final Answer:
- Statement 1 is true.
- Statement 2 is true.
- Statement 2 is the correct explanation for Statement 1.

Thus, the correct option is that both statements are true, and Statement 2 explains Statement 1.
