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. BDYW
B. CEXZ
C. DFYW
D. EGXV

Answer

To solve the problem, we need to identify the odd group of letters among the four given groups based on a certain pattern. The groups are:

1. (B, D, Y, W)
2. (C, E, X, Z)
3. (D, F, Y, W)
4. (C, E, G, X, V)

Let's analyze each group step by step:

### Step 1: Analyze Group 1 (B, D, Y, W)
- B is the 2nd letter of the alphabet.
- D is the 4th letter of the alphabet.
- Y is the 25th letter of the alphabet.
- W is the 23rd letter of the alphabet.

**Pattern**:
- From B (2) to D (4), we add 2.
- From Y (25) to W (23), we subtract 2.

### Step 2: Analyze Group 2 (C, E, X, Z)
- C is the 3rd letter of the alphabet.
- E is the 5th letter of the alphabet.
- X is the 24th letter of the alphabet.
- Z is the 26th letter of the alphabet.

**Pattern**:
- From C (3) to E (5), we add 2.
- From X (24) to Z (26), we add 2.

### Step 3: Analyze Group 3 (D, F, Y, W)
- D is the 4th letter of the alphabet.
- F is the 6th letter of the alphabet.
- Y is the 25th letter of the alphabet.
- W is the 23rd letter of the alphabet.

**Pattern**:
- From D (4) to F (6), we add 2.
- From Y (25) to W (23), we subtract 2.

### Step 4: Analyze Group 4 (C, E, G, X, V)
- C is the 3rd letter of the alphabet.
- E is the 5th letter of the alphabet.
- G is the 7th letter of the alphabet.
- X is the 24th letter of the alphabet.
- V is the 22nd letter of the alphabet.

**Pattern**:
- From C (3) to E (5), we add 2.
- From E (5) to G (7), we add 2.
- From X (24) to V (22), we subtract 2.

### Conclusion:
Now, let's summarize the patterns:
- Groups 1 and 3 have a consistent pattern of adding 2 to the first two letters and subtracting 2 from the last two letters.
- Group 2 has a consistent pattern of adding 2 for both pairs.
- Group 4 has a mixed pattern of adding 2 for the first three letters and subtracting 2 for the last pair.

**Odd Group**: Group 2 (C, E, X, Z) is the odd one out because it does not follow the same subtracting pattern as the others.

### Final Answer:
The odd one out is **(C, E, X, Z)**.
