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. VRT
B. RMP
C. YUW
D. FBD

Explanation

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

### Step-by-Step Solution:

1. **Identify the Groups**: The groups of letters provided are:
- Option A: vrt
- Option B: rmb
- Option C: yuw
- Option D: fbd

2. **Analyze Option A (vrt)**:
- v to r: Move backwards 4 places (v → u → t → s → r)
- r to t: Move forwards 2 places (r → s → t)

So, the pattern for option A is: **-4, +2**.

3. **Analyze Option B (rmb)**:
- r to m: Move backwards 5 places (r → q → p → o → n → m)
- m to b: Move backwards 11 places (m → l → k → j → i → h → g → f → e → d → c → b)

The pattern for option B is: **-5, -11**.

4. **Analyze Option C (yuw)**:
- y to u: Move backwards 4 places (y → x → w → v → u)
- u to w: Move forwards 2 places (u → v → w)

The pattern for option C is: **-4, +2**.

5. **Analyze Option D (fbd)**:
- f to b: Move backwards 4 places (f → e → d → c → b)
- b to d: Move forwards 2 places (b → c → d)

The pattern for option D is: **-4, +2**.

6. **Compare the Patterns**:
- Option A: -4, +2
- Option B: -5, -11
- Option C: -4, +2
- Option D: -4, +2

From the analysis, we can see that options A, C, and D follow the same pattern of **-4, +2**, while option B follows a different pattern of **-5, -11**.

7. **Conclusion**: The group that is different is **Option B (rmb)**.

### Final Answer:
The option that is different is **Option B (rmb)**.
