B. STATEMENT-1 I true, STATENENT-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 analyze the statements provided in the question, let's break down the reasoning step by step.

### Step-by-Step Solution:

1. **Understanding Statement 1**:
- The first statement claims that the hydrogen atoms in ethyne (C₂H₂) are acidic in nature.
- Ethyne has the structure H-C≡C-H, where the carbon atoms are sp-hybridized.
- Acidity refers to the ability of a substance to donate a proton (H⁺). In this case, the hydrogen atoms can be released as protons.

2. **Analyzing Acidity**:
- When a hydrogen atom is removed from ethyne, it forms a negative ion (C≡C⁻).
- The stability of this negative ion is crucial. The more stable the negative charge, the stronger the acid.
- The sp-hybridization of carbon leads to a higher electronegativity of the carbon atoms compared to sp² or sp³ hybridized carbons.

3. **Understanding Statement 2**:
- The second statement asserts that the sp-hybridization of carbon atoms makes them more electronegative.
- In sp-hybridization, the s character is 50% (as opposed to 33% in sp² and 25% in sp³), which increases the electronegativity of the carbon atoms.
- This higher electronegativity contributes to the stability of the negative charge when hydrogen is removed, confirming the acidic nature of the hydrogen atoms in ethyne.

4. **Conclusion**:
- Both statements are true:
- Statement 1 is true because the hydrogen atoms in ethyne are indeed acidic.
- Statement 2 is true because sp-hybridization increases the electronegativity of carbon, which stabilizes the negative charge.
- Therefore, the correct conclusion is that both statements are true, and the relationship between them is that the sp-hybridization contributes to the acidity of the hydrogen atoms.

### Final Answer:
Both Statement 1 and Statement 2 are true, and Statement 2 explains Statement 1.
