Explanation:
Detailed explanation-1: -When numbers are written in scientific notation, then the number of digits between 1 and 10 gives the number of significant figures. Thus, the number 6.02×10²³ contains 3 significant figures. All the three digits (6, 0 and 2) are significant. Hence, option B is correct.
Detailed explanation-2: -We are asked how many significant figures are in a measurement of 10.00. As 1 is a non-zero digit, it will be significant. As all our zeros follow a non-zero digit, they will also be significant. As a result, all 4 digits are significant.
