DIRECTION: In the following questions, a statement of assertion (A) is followed by a statement of reason (R). Mark the correct choice as:
(a) Both assertion (A) and reason (R) is true and reason \( (\mathrm{R}) \) is the correct explanation of assertion (A).
(b) Both assertion (A) and reason (R) is true but reason (R) is not the correct explanation of assertion (A).
(c) Assertion (A) is true but reason (R) is false.
(d) Assertion (A) is false but reason (R) is true.
Assertion: If the circumference of two circles are in the ratio \( 2: 3 \), then the ratio of their areas is \( 4: 9 \).
- Reason: The circumference of a circle of radius \( r \) is \( 2 \pi \mathrm{r} \) and its area is \( \pi \mathrm{r}^{2} \).
