The number of significant figure in 60.001 are

Options

A. 5
B. 6
C. 3
D. 2

Explanation

To determine the number of significant figures in the number 60.001, we will follow these steps:

### Step-by-Step Solution:

1. **Identify Non-Zero Digits**:
- In the number 60.001, the non-zero digits are 6 and 1.

2. **Count the Non-Zero Digits**:
- There are 2 non-zero digits (6 and 1).

3. **Identify and Count Zeros**:
- There are two types of zeros to consider:
- Leading zeros (zeros before the first non-zero digit) do not count as significant figures.
- Zeros between non-zero digits and trailing zeros after the decimal point do count as significant figures.
- In 60.001, the zeros are:
- The zero after 6 (between 6 and 1) is significant.
- The zero before 1 (after the decimal) is also significant.
- Therefore, we have:
- 1 zero between 6 and 1 (which is significant).
- 2 zeros after the decimal point (0.001, both of which are significant).

4. **Total Count of Significant Figures**:
- Adding these together:
- Non-zero digits: 2 (6 and 1)
- Significant zeros: 3 (1 zero between 6 and 1, and 2 zeros after the decimal)
- Total significant figures = 2 (non-zero) + 3 (significant zeros) = 5.

### Conclusion:
The total number of significant figures in the number 60.001 is **5**.
