Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R: Assertion A: If the percentage error in the measurement of radius of the sphere is 0.3%, then the permissible percentage error in its surface area is 0.6%. Reason R: The permissible error is calculated by \Delta A/A = 4\Delta r/r. In the light of the above statements, choose the correct answer from the options given below:
A
A is true but R is false.
B
A is false but R is true.
C
Both A and R are true and R is the correct explanation of A.
D
Both A and R are true but R is NOT the correct explanation of A.
