1.	Assertion: The number `1.202 `has four significant figure and the number `0.0024` has two significant figure. Reason: All the zero digits are significant.A. If both assertion and reason are true and reason is the correct explation of assertion.B. If both assertion but reason is not the correct explanation of assertion.C. If assertion is true but reason is false.D. If both assertion and reason are false.
Answer» Correct Answer - b The number of significant figure in `1.202` is four and the number of significant figure inn `0.0024` is two. All non zero digits are significant. All zero occurring where the decimal point is. If the number is less then one, the zero on the ring of decimal point and to the left of first non - zero digit are not significant.
