Answer

To solve the question of matching the crops with their corresponding insect pest-resistant varieties, we will go through each crop and identify the correct variety from Column II.

### Step-by-Step Solution:

1. **Identify the Crop and its Resistant Variety**:
- **Flat Bean**: We need to find which variety from Column II is resistant to pests affecting flat beans.
- **Okra (Bhindi)**: Next, we look for the variety that is resistant to pests affecting okra.
- **Brassica**: Finally, we identify the variety that is resistant to pests affecting Brassica.

2. **Match Each Crop with the Correct Variety**:
- **For Flat Bean**:
- The variety that is resistant to pests affecting flat beans is **Pusa Sem-2**.
- Therefore, the match is **Flat Bean - Pusa Sem-2** (A - ii).

- **For Okra (Bhindi)**:
- The variety that is resistant to pests affecting okra is **Pusa Sawani**.
- Thus, the match is **Okra - Pusa Sawani** (B - iii).

- **For Brassica**:
- The variety that is resistant to pests affecting Brassica is **Pusa Gaurav**.
- Hence, the match is **Brassica - Pusa Gaurav** (C - i).

3. **Summarize the Matches**:
- A. Flat Bean - Pusa Sem-2 (ii)
- B. Okra (Bhindi) - Pusa Sawani (iii)
- C. Brassica - Pusa Gaurav (i)

4. **Select the Correct Option**:
- Based on the matches, the correct option is:
- A - ii
- B - iii
- C - i

### Final Answer:
The correct matches are:
- A (Flat Bean) - ii (Pusa Sem-2)
- B (Okra) - iii (Pusa Sawani)
