C. Four
D. Two

Answer

To determine the number of significant figures in the measured value 0.0204, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Number**: The given number is 0.0204.

2. **Recognize the Decimal Point**: The presence of a decimal point indicates that we need to consider the rules for counting significant figures in decimal numbers.

3. **Analyze Leading Zeros**: In decimal numbers, any zeros that precede the first non-zero digit are not considered significant. In the number 0.0204, the leading zeros (the two zeros before the 2) are not significant.

4. **Count the Significant Figures**: After removing the leading zeros, we are left with the digits 2, 0, and 4. All of these digits are significant:
- The digit '2' is significant.
- The digit '0' (which is between non-zero digits) is significant.
- The digit '4' is significant.

5. **Total Count**: Therefore, the total number of significant figures in 0.0204 is 3.

### Final Answer:
The number of significant figures in the measured value 0.0204 is **3**.
