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. AEGC
B. HLNJ
C. OSVQ
D. VZBX

Explanation

To solve the question where we need to identify the group of letters that is different from the others, we will analyze each option step by step.

### Step 1: Analyze Option A - G to C
- G is the 7th letter of the alphabet.
- C is the 3rd letter of the alphabet.
- The difference is: 7 - 3 = 4 (moving backwards).
- So, G to C is a backward movement of 4 positions.

### Step 2: Analyze Option A - H to L
- H is the 8th letter of the alphabet.
- L is the 12th letter of the alphabet.
- The difference is: 12 - 8 = 4 (moving forwards).
- So, H to L is a forward movement of 4 positions.

### Step 3: Analyze Option A - L to N
- L is the 12th letter of the alphabet.
- N is the 14th letter of the alphabet.
- The difference is: 14 - 12 = 2 (moving forwards).
- So, L to N is a forward movement of 2 positions.

### Step 4: Analyze Option A - N to J
- N is the 14th letter of the alphabet.
- J is the 10th letter of the alphabet.
- The difference is: 14 - 10 = 4 (moving backwards).
- So, N to J is a backward movement of 4 positions.

### Step 5: Analyze Option B - O to S
- O is the 15th letter of the alphabet.
- S is the 19th letter of the alphabet.
- The difference is: 19 - 15 = 4 (moving forwards).
- So, O to S is a forward movement of 4 positions.

### Step 6: Analyze Option B - S to V
- S is the 19th letter of the alphabet.
- V is the 22nd letter of the alphabet.
- The difference is: 22 - 19 = 3 (moving forwards).
- So, S to V is a forward movement of 3 positions.

### Step 7: Analyze Option B - V to Q
- V is the 22nd letter of the alphabet.
- Q is the 17th letter of the alphabet.
- The difference is: 22 - 17 = 5 (moving backwards).
- So, V to Q is a backward movement of 5 positions.

### Step 8: Analyze Option C - V to Z
- V is the 22nd letter of the alphabet.
- Z is the 26th letter of the alphabet.
- The difference is: 26 - 22 = 4 (moving forwards).
- So, V to Z is a forward movement of 4 positions.

### Step 9: Analyze Option C - Z to B
- Z is the 26th letter of the alphabet.
- B is the 2nd letter of the alphabet.
- The difference is: 26 - 2 = 24 (moving backwards).
- So, Z to B is a backward movement of 24 positions.

### Step 10: Analyze Option C - B to X
- B is the 2nd letter of the alphabet.
- X is the 24th letter of the alphabet.
- The difference is: 24 - 2 = 22 (moving forwards).
- So, B to X is a forward movement of 22 positions.

### Conclusion
- In options A and B, the movements are consistent with a pattern of alternating between forward and backward movements with smaller differences.
- However, in option C, the movements from Z to B and B to X are significantly larger and do not follow the same pattern as the other options.

Thus, the group of letters that is different is **Option C**.
