The number of signicant gures in 0.00150 is: A. 2 B. 3 C. 4 D. 5 E. 6

In number 0.00150, the first two zeros after the decimal point are not significant as they are not final or trailing zeros. While the zero after 5 is a trailing zero, so it is a significant figure. Therefore, there are three significant figures.Hence, option (B) is correct.
