D. 5780

Answer

To find the wrong number in the series: 1, 12, 120, 960, 5780, 23040, 46080, we will analyze the pattern in the series step by step.

### Step-by-Step Solution:

1. **Identify the Pattern**:
- Start with the first number, which is 1.
- The second number is 12.
- To get from 1 to 12, we multiply by 12:
\[ 1 \times 12 = 12 \]

2. **Continue the Pattern**:
- The third number is 120.
- To get from 12 to 120, we multiply by 10:
\[ 12 \times 10 = 120 \]

3. **Next Number**:
- The fourth number is 960.
- To get from 120 to 960, we multiply by 8:
\[ 120 \times 8 = 960 \]

4. **Check the Next Number**:
- The fifth number is 5780.
- To find the next number in the pattern, we should multiply 960 by 6:
\[ 960 \times 6 = 5760 \]
- However, the number given is 5780, which is not equal to 5760.

5. **Identify the Wrong Number**:
- Since 5780 does not fit the pattern, it is the wrong number in the series.

6. **Verify the Next Number**:
- The sixth number is 23040.
- If we were to continue the pattern correctly, we would multiply 5760 (the correct number) by 4:
\[ 5760 \times 4 = 23040 \]
- This confirms that if we replace 5780 with 5760, the series continues correctly.

### Conclusion:
The wrong number in the series is **5780**.
