Answer

To solve the problem of picking the odd one out from the list of numbers: 28, 44, 68, 80, and 92, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Numbers**: We have the numbers: 28, 44, 68, 80, and 92.

2. **Check for Multiples of 4**: We will check if these numbers are multiples of 4.
- 28 ÷ 4 = 7 (which is an integer, so 28 is a multiple of 4)
- 44 ÷ 4 = 11 (which is an integer, so 44 is a multiple of 4)
- 68 ÷ 4 = 17 (which is an integer, so 68 is a multiple of 4)
- 80 ÷ 4 = 20 (which is an integer, so 80 is a multiple of 4)
- 92 ÷ 4 = 23 (which is an integer, so 92 is a multiple of 4)

3. **List the Multiples of 4**: All numbers are multiples of 4:
- 28 = 4 × 7
- 44 = 4 × 11
- 68 = 4 × 17
- 80 = 4 × 20
- 92 = 4 × 23

4. **Determine Odd and Even Multiples**: Next, we will check if these multiples are odd or even.
- 28 (4 × 7) - odd multiple of 4
- 44 (4 × 11) - odd multiple of 4
- 68 (4 × 17) - odd multiple of 4
- 80 (4 × 20) - even multiple of 4
- 92 (4 × 23) - odd multiple of 4

5. **Identify the Odd One Out**: From the above analysis, we see that 80 is the only even multiple of 4, while all other numbers are odd multiples of 4.

6. **Conclusion**: Therefore, the odd one out is **80**.

### Final Answer:
The correct option is **C. 80**.
