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. BCD
B. NPR
C. KLM
D. RQP

Answer

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

Let's break down the options:

1. **Option 1: B, C, D**
- The letters are consecutive:
- B to C (1 step forward)
- C to D (1 step forward)

2. **Option 2: (1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13)**
- This option seems to represent numbers rather than letters. It does not follow the same pattern of letter progression.

3. **Option 3: K, L, M**
- The letters are consecutive:
- K to L (1 step forward)
- L to M (1 step forward)

4. **Option 4: R, Q, P**
- The letters are consecutive but in reverse:
- R to Q (1 step backward)
- Q to P (1 step backward)

Now, let's summarize the patterns:
- **Option 1** (B, C, D) follows a pattern of +1.
- **Option 2** (1, 2, 3...) does not follow the letter pattern.
- **Option 3** (K, L, M) follows a pattern of +1.
- **Option 4** (R, Q, P) follows a pattern of -1.

From the analysis, we can see that Options 1, 3, and 4 involve a change of 1 step (either forward or backward), while Option 2 is completely different as it represents numbers instead of letters.

Thus, the odd one out is **Option 2**.

### Final Answer:
**Option 2 is the odd one out.**
