Circle A is shown with a central angle marked 30 degrees and the radius marked 5 inches.

The area for a sector of a circle is $A=\frac{\theta}{360}*\pi r^2$ . If our angle is 30 and our radius is 5, that fits in like so: $A=\frac{30}{360}\pi (5)^2$ . It appears that the first choice is what we want except you forgot to square all the radii.
