The Correct Option is B
Solution and Explanation
Concept:
Rules for significant figures:
• Leading zeros are not significant.
• Zeros between non-zero digits are significant.
• Trailing zeros after a decimal point are significant.
• The power of \(10\) does not affect the number of significant figures.
Step 1: Count the significant figures. In \[ 0.0010200 \] the significant digits are \[ 1,\;0,\;2,\;0,\;0 \] Hence, \[ \boxed{5\text{ significant figures}} \]
Step 2: Final conclusion. The factor \(10^{5}\) does not change the count of significant figures. Therefore, the correct option is \(\boxed{(B)}\).
