(a) If both assertion and reason are true and the reason is the correct explanation of the assertion.
(b) If both assertion and reason are true but reason is not the correct explanation of the assertion.
(c) If assertion is true but reason is false.
(d) If the assertion and reason both are false.
(e) If assertion is false but reason is true.
Assertion: The error in the measurement of radius of the sphere is \( 0.3 \% \) The permissible error in its surface area is \( 0.6 \% \).

Reason : The permissible error is calculated by the formula \( \frac{\Delta A}{A}=\frac{4 \Delta r}{r} \).
