Explanation:

Step1: Recall significant - figures rule for scientific notation

In scientific notation \(a\times10^{n}\), the significant figures are determined by the digits in \(a\).

Step2: Identify digits in \(a\)

For \(1.52\times 10^{1}\text{ kg}\), the value of \(a = 1.52\). The digits \(1\), \(5\), and \(2\) are significant.

Answer:

B. Three significant figures
