The Correct Option is D
Solution and Explanation
Step 1: Count significant figures
- I) 0.0063 has 2 significant figures (leading zeros not counted).
- II) 132.00 has 5 significant figures (trailing zeros counted after decimal).
- III) 1004 has 4 significant figures (zeros between digits counted).
Step 2: Conclusion
The significant figures are 2, 5, and 4 respectively.
- I) 0.0063 has 2 significant figures (leading zeros not counted).
