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

Options

A. XW
B. FG
C. ML
D. PO

Answer

To solve the problem, we need to analyze the given groups of letters and identify the one that is different from the others based on their arrangement or properties.

### Step-by-Step Solution:

1. **Identify the Groups**: We have four groups of letters:
- Group 1: X and W
- Group 2: F and G
- Group 3: M and L
- Group 4: P and O

2. **Assign Numerical Values**: We can assign numerical values to each letter based on their position in the English alphabet:
- X = 24, W = 23
- F = 6, G = 7
- M = 13, L = 12
- P = 16, O = 15

3. **Analyze Each Group**:
- **Group 1 (X and W)**: X (24) and W (23) are in reverse order (24, 23).
- **Group 2 (F and G)**: F (6) and G (7) are consecutive numbers (6, 7).
- **Group 3 (M and L)**: M (13) and L (12) are in reverse order (13, 12).
- **Group 4 (P and O)**: P (16) and O (15) are in reverse order (16, 15).

4. **Identify the Odd One Out**:
- Groups 1, 3, and 4 are in reverse order, while Group 2 (F and G) is in consecutive order.
- Therefore, the odd one out is **Group 2: F and G**.

### Conclusion:
The group that is different from the others is **F and G** because it consists of consecutive letters, while the other groups consist of letters in reverse order.
