If (d) denotes the area of a circle with diameter d, then which of the following is equal to

(4)* (6) ?

(A) 10

(B) 12

(C) 24

(D) π ⋅ 12

(E) π ⋅ 24

I don't think any of the answers are correct.

If (d) denotes the area of a circle with diameter d, then for (4) the radius of circle is 4/2 or 2, and the area of the circle with radius of 2 is 4pie

For (6) the radius of circle is 6/2 or 3, and the area of the circle with radius of 3 is 9pie

(4)*(6) would be 36(pie)^2, which I didn't find in any of the answer choices. Are you sure the question is correct?
