In each of the following questions, five groups of letters are given. Four of them are alike in a certain way while one is different. Choose the odd one.

Options

A. HGF
B. XWV
C. NML
D. OPQ

Answer

To solve the problem, we need to analyze the groups of letters provided and identify which one does not follow the same pattern as the others.

### Step-by-Step Solution:

1. **Identify the Groups**: The groups given are:
- Group 1: HDF
- Group 2: XWV
- Group 3: NML
- Group 4: OPQ

2. **Convert Letters to Their Position in the Alphabet**:
- H = 8, D = 4, F = 6
- X = 24, W = 23, V = 22
- N = 14, M = 13, L = 12
- O = 15, P = 16, Q = 17

3. **Analyze Each Group**:
- **Group 1 (HDF)**:
- Positions: 8 (H), 4 (D), 6 (F)
- Order: 8, 6, 4 (not in a consecutive order)
- **Group 2 (XWV)**:
- Positions: 24 (X), 23 (W), 22 (V)
- Order: 24, 23, 22 (in reverse consecutive order)
- **Group 3 (NML)**:
- Positions: 14 (N), 13 (M), 12 (L)
- Order: 14, 13, 12 (in reverse consecutive order)
- **Group 4 (OPQ)**:
- Positions: 15 (O), 16 (P), 17 (Q)
- Order: 15, 16, 17 (in consecutive order)

4. **Determine the Odd One Out**:
- Groups 2 and 3 (XWV and NML) are in reverse consecutive order.
- Group 1 (HDF) does not follow a clear pattern of reverse order.
- Group 4 (OPQ) is in consecutive order, which is different from the others.

5. **Conclusion**:
- The odd group is **OPQ** because it is the only group that is in a consecutive order, while the others are in reverse order.

### Final Answer:
The odd one out is **OPQ**.
