Concept:Find the value of the given numerical fraction, then round the result to three significant figures.Explanation:First, multiply the values in the numerator.$12.02 \times 20.06 = 241.1212$Then, multiply the values in the denominator.$26.04 \times 60.06 = 1563.9624$This gives the fraction:$\frac{241.1212}{1563.9624}$Now, divide the numerator by the denominator.$\frac{241.1212}{1563.9624} = 0.154173\ldots$To round to three significant figures, examine the fourth significant digit, which is $1$.Since $1$ is less than $5$, the third significant digit remains unchanged.Therefore, $0.154173\ldots \approx 0.154$The correct answer is option B.Answer:B. 0.154
