a. Both assertion and reason are true and reason is the correct explanation of assertion.
b. Both assertion and reason are true but reason is not the correct explanation of assertion.
c. Assertion is true but reason is false.
d. Assertion is false but reason is true.
Assertion: If the volumes of two spheres are in the ratio \( 27: 8 \), then their surface areas are in the ratio \( 3: 2 \).

Reason: Volume of the sphere \( =\frac{4}{3} \pi r^{3} \) and its surface area \( =4 \pi r^{2} \).
