Answer

To solve the problem of matching the number of significant figures with the given numbers, we will analyze each number step by step.

### Step 1: Analyze the number 6.022 x 10^23
- **Significant Figures**: All non-zero digits are significant.
- The digits are 6, 0, 2, 2.
- The zero is significant because it is between two non-zero digits.
- **Total Significant Figures**: 4

### Step 2: Analyze the number 0.0085
- **Significant Figures**: Leading zeros are not significant.
- The significant digits are 8 and 5.
- **Total Significant Figures**: 2

### Step 3: Analyze the number 2.850
- **Significant Figures**: All non-zero digits and any zeros between them or following a decimal point are significant.
- The digits are 2, 8, 5, and the trailing zero.
- **Total Significant Figures**: 4

### Step 4: Analyze the number 0.0200
- **Significant Figures**: Leading zeros are not significant, but trailing zeros after a decimal point are significant.
- The significant digits are 2, and the two trailing zeros.
- **Total Significant Figures**: 3

### Summary of Findings:
- (A) 1 significant figure: None of the numbers match.
- (B) 2 significant figures: Matches with (q) 0.0085.
- (C) 3 significant figures: Matches with (s) 0.0200.
- (D) 5 significant figures: None of the numbers match.

### Final Matches:
- (A) - None
- (B) - (q) 0.0085
- (C) - (s) 0.0200
- (D) - None
