Choose the number pair/group which is different from others.

Options

A. `12-72`
B. `24-48`
C. `60-74`
D. `84-96`

Explanation

To solve the problem of identifying the number pair/group that is different from the others, we will analyze each option based on their factors.

### Step-by-Step Solution:

1. **Examine Option A (12, 72)**:
- The numbers can be expressed as:
- \( 12 = 12 \times 1 \)
- \( 72 = 12 \times 6 \)
- Both numbers share a common factor of 12.

2. **Examine Option B (24, 48)**:
- The numbers can be expressed as:
- \( 24 = 12 \times 2 \)
- \( 48 = 12 \times 4 \)
- Both numbers share a common factor of 12.

3. **Examine Option C (60, 74)**:
- The numbers can be expressed as:
- \( 60 = 12 \times 5 \)
- \( 74 = 37 \times 2 \)
- Here, 60 has a common factor of 12, but 74 does not share this factor. The highest common factor of these two numbers is not 12.

4. **Examine Option D (84, 96)**:
- The numbers can be expressed as:
- \( 84 = 12 \times 7 \)
- \( 96 = 12 \times 8 \)
- Both numbers share a common factor of 12.

5. **Conclusion**:
- Options A, B, and D all have pairs that share a common factor of 12. However, option C (60 and 74) does not share this common factor. Therefore, the odd one out is **Option C (60, 74)**.

### Final Answer:
The number pair/group which is different from others is **Option C (60, 74)**.
