The Correct Option is B
Solution and Explanation
Step 1: Recall the rules of significant figures.
Leading zeros appearing before the first non-zero digit are not counted as significant figures.
In the number \[ 0.00005041, \] the zeros before the digit \(5\) are only placeholders and are not significant.
Step 2: Identify the significant digits.
The significant digits are \[ 5,\;0,\;4,\;1 \] The zero between \(5\) and \(4\) is significant because it occurs between non-zero digits.
Step 3: Count the significant figures.
Thus, the total number of significant figures is \[ 4 \]
Step 4: Final conclusion.
Therefore, the number \(0.00005041\ \text{J}\) contains \[ \boxed{4} \] significant figures.
