1. Assertion: Number of significant digit in 0.002 is one and that in 0.500 is three.Reason: If number is less than 1, then zeroes before the non-zero numbers are not significant and zeroes after non-zero number are significant.
A
Both Assertion & Reason are true and the reason is the correct explanation of the assertion
B
Both Assertion & Reason are true but the reason is not the correct explanation of the assertion
C
Assertion is true statement but Reason is false
D
Both Assertion and Reason are false statements
Explanation
Leading zeros are never significant. Trailing zeros in a decimal number are significant. Hence, 0.002 has 1 (the '2') and 0.500 has 3 (the '5' and two '0's).
