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. DE
B. PQ
C. TU
D. MO

Answer

To solve the problem, we need to identify the odd group of letters among the given options based on a specific pattern. Let's analyze the groups step by step.

### Step-by-Step Solution:

1. **Identify the Groups**: The groups given are:
- Group 1: D, E
- Group 2: P, Q
- Group 3: T, U
- Group 4: M, O

2. **Check for Consecutive Letters**:
- **Group 1 (D, E)**: D is the 4th letter and E is the 5th letter in the alphabet. They are consecutive.
- **Group 2 (P, Q)**: P is the 16th letter and Q is the 17th letter in the alphabet. They are consecutive.
- **Group 3 (T, U)**: T is the 20th letter and U is the 21st letter in the alphabet. They are consecutive.
- **Group 4 (M, O)**: M is the 13th letter and O is the 15th letter in the alphabet. They are NOT consecutive because N (14th letter) is missing between them.

3. **Conclusion**: Since three groups (D, E), (P, Q), and (T, U) consist of consecutive letters, while (M, O) does not, we can conclude that Group 4 is the odd one out.

### Final Answer:
The odd group is **M, O**.
