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. VX
B. MO
C. PR
D. FG

Answer

To solve the problem, we need to analyze the groups of letters provided and determine which group is the odd one out based on a specific pattern or relationship among the letters.

### Step-by-Step Solution:

1. **Identify the Groups**: We have four groups of letters:
- Group 1: (A, B, C, D, E, F, G, H, I, J, K, L, M)
- Group 2: (1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13)
- Group 3: (N, O, P, Q, R, S, T, U, V, W, X, Y, Z)
- Group 4: (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26)

2. **Analyze the First Group**: The first group consists of letters from A to M. This group contains the first 13 letters of the English alphabet.

3. **Analyze the Second Group**: The second group consists of numbers from 1 to 13. This group contains the first 13 natural numbers.

4. **Analyze the Third Group**: The third group consists of letters from N to Z. This group contains the letters from N to Z, which are the last 13 letters of the English alphabet.

5. **Analyze the Fourth Group**: The fourth group consists of numbers from 14 to 26. This group contains the numbers corresponding to the letters N to Z.

6. **Identify the Pattern**:
- The first group (A to M) and the second group (1 to 13) are both the first half of the alphabet and the first half of the natural numbers, respectively.
- The third group (N to Z) and the fourth group (14 to 26) are both the second half of the alphabet and the second half of the natural numbers, respectively.

7. **Determine the Odd One Out**:
- The first two groups (letters A to M and numbers 1 to 13) are related as the first half of their respective sequences.
- The last two groups (letters N to Z and numbers 14 to 26) are related as the second half of their respective sequences.
- Since the first group (A to M) and the second group (1 to 13) are both from the first half, while the third group (N to Z) and the fourth group (14 to 26) are from the second half, the odd one out is the second group (1, 2, 3, ..., 13) because it is the only group that consists of numbers instead of letters.

### Conclusion:
The odd one out is the second group: **(1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13)**.
