Number of significant figures present in 0.2003 are

Options

A. 1
B. 2
C. 3
D. 4

Explanation

To determine the number of significant figures in the number 0.2003, we will follow the rules of significant figures step by step.

### Step-by-Step Solution:

1. **Identify the number**: We are given the number 0.2003.

2. **Analyze the leading zeros**: The zeros that appear before the first non-zero digit (in this case, the two zeros before the '2') are not significant. Therefore, we can ignore these leading zeros.

3. **Identify the non-zero digits**: The digits '2', '3' are non-zero and are always significant.

4. **Check the zeros between non-zero digits**: The '0' in the middle (between '2' and '3') is significant because it is sandwiched between two non-zero digits.

5. **Count the significant figures**:
- The significant figures in 0.2003 are:
- '2' (significant)
- '0' (between non-zero digits, significant)
- '0' (leading zeros before the decimal are not significant)
- '3' (significant)
- Therefore, the significant figures are: 2, 0, 0, 3.

6. **Final count**: We have a total of 4 significant figures in the number 0.2003.

### Conclusion:
The number of significant figures present in 0.2003 is **4**.
