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. EFGIK
B. CDFIM
C. BCEHL
D. ABDGK

Answer

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

### Step-by-Step Solution:

1. **Identify the Groups**: The groups provided are:
- Group 1: E, F, G, I, K
- Group 2: C, D, F, I, M
- Group 3: B, C, E, H, L
- Group 4: A, B, D, G, K

2. **Analyze Group 1 (E, F, G, I, K)**:
- E to F: +1 step
- F to G: +1 step
- G to I: +2 steps (G to H to I)
- I to K: +2 steps (I to J to K)
- **Pattern**: +1, +1, +2, +2

3. **Analyze Group 2 (C, D, F, I, M)**:
- C to D: +1 step
- D to F: +2 steps (D to E to F)
- F to I: +3 steps (F to G to H to I)
- I to M: +4 steps (I to J to K to L to M)
- **Pattern**: +1, +2, +3, +4

4. **Analyze Group 3 (B, C, E, H, L)**:
- B to C: +1 step
- C to E: +2 steps (C to D to E)
- E to H: +3 steps (E to F to G to H)
- H to L: +4 steps (H to I to J to K to L)
- **Pattern**: +1, +2, +3, +4

5. **Analyze Group 4 (A, B, D, G, K)**:
- A to B: +1 step
- B to D: +2 steps (B to C to D)
- D to G: +3 steps (D to E to F to G)
- G to K: +4 steps (G to H to I to J to K)
- **Pattern**: +1, +2, +3, +4

6. **Identify the Odd One Out**:
- Groups 2, 3, and 4 follow the same pattern of increasing steps (+1, +2, +3, +4).
- Group 1 does not follow this pattern; it has a different step sequence (+1, +1, +2, +2).
- Therefore, the odd one out is **Group 1: E, F, G, I, K**.

### Final Answer:
The odd one out is **Group 1: E, F, G, I, K**.
