D. Statement-1 is False, Statement-2 is True.

Explanation

To solve the problem, we need to analyze the acidity of ortho-nitrophenol and ortho-methoxyphenol based on the influence of their substituents on the stability of their conjugate bases.

### Step-by-Step Solution:

1. **Identify the Structures**:
- Draw the structure of **ortho-nitrophenol** (2-nitrophenol):
- It consists of a phenolic ring with a hydroxyl group (-OH) and a nitro group (-NO2) at the ortho position.
- Draw the structure of **ortho-methoxyphenol** (2-methoxyphenol):
- It consists of a phenolic ring with a hydroxyl group (-OH) and a methoxy group (-OCH3) at the ortho position.

2. **Determine the Conjugate Bases**:
- For **ortho-nitrophenol**, when it donates a proton (H+), the conjugate base formed is:
- \[ \text{C}_6\text{H}_4(\text{NO}_2)\text{O}^- \]
- For **ortho-methoxyphenol**, when it donates a proton, the conjugate base formed is:
- \[ \text{C}_6\text{H}_4(\text{OCH}_3)\text{O}^- \]

3. **Analyze Stability of Conjugate Bases**:
- The stability of the conjugate base is crucial for determining acidity.
- The **nitro group (-NO2)** is a strong electron-withdrawing group due to its -M (minus mesomeric) effect. This decreases electron density on the ring and stabilizes the negative charge on the oxygen in the conjugate base.
- The **methoxy group (-OCH3)** is an electron-donating group due to its +M (plus mesomeric) effect. This increases electron density on the ring and destabilizes the negative charge on the oxygen in the conjugate base.

4. **Compare Acidity**:
- Since the conjugate base of ortho-nitrophenol is more stable due to the electron-withdrawing effect of the nitro group, ortho-nitrophenol is more acidic than ortho-methoxyphenol.
- Conversely, the conjugate base of ortho-methoxyphenol is less stable due to the electron-donating effect of the methoxy group, making it less acidic.

5. **Evaluate the Statements**:
- **Statement 1**: "Ortho nitro phenol is more acidic than ortho methoxy phenol." - This statement is **true**.
- **Statement 2**: "NO2 is a deactivating group while OCH3 is an activating group." - This statement is also **true**.

6. **Conclusion**:
- Both statements are true, and Statement 2 correctly explains Statement 1. Therefore, the answer is that both statements are true, and Statement 2 is the correct explanation for Statement 1.

### Final Answer:
Both statements are true, and Statement 2 is the correct explanation for Statement 1.
