In each of these question, four groups of letters are given. Three of them are alike in a certain way while one is different select the one which is different.

Options

A. BCD
B. NPR
C. KLM
D. RQP

Explanation

To solve the problem of identifying the group of letters that is different from the others, we will analyze each option step by step.

### Step 1: Analyze the first option (B, C, D)
- The letters are B, C, D.
- From B to C, we add 1 (B + 1 = C).
- From C to D, we add 1 (C + 1 = D).
- This sequence is consecutive.

### Step 2: Analyze the second option (N, P, R)
- The letters are N, P, R.
- From N to P, we add 2 (N + 2 = P).
- From P to R, we add 2 (P + 2 = R).
- This sequence is not consecutive by 1, but rather by 2.

### Step 3: Analyze the third option (K, L, M)
- The letters are K, L, M.
- From K to L, we add 1 (K + 1 = L).
- From L to M, we add 1 (L + 1 = M).
- This sequence is consecutive.

### Step 4: Analyze the fourth option (R, Q, P)
- The letters are R, Q, P.
- From R to Q, we subtract 1 (R - 1 = Q).
- From Q to P, we subtract 1 (Q - 1 = P).
- This sequence is also consecutive.

### Conclusion
- The first option (B, C, D) is consecutive.
- The third option (K, L, M) is consecutive.
- The fourth option (R, Q, P) is consecutive.
- The second option (N, P, R) is different because it involves adding 2 instead of adding 1 or subtracting 1.

Thus, the group of letters that is different is **Option B (N, P, R)**.
