I think there is agreement that A is the answer. The fact that we do have specific numbers means D cannot be the answer in any case.

We have precise refernces

We know the radius that is 4. Therefore, the other radius is also 4. An d the diameter is 2R=8

The height of the triangle is also the radius, which is 4

We can calculate the area of the 1 and 2 triangle

\(A=\frac{ 1}{2}* b*h=\frac{1}{2}*4*4=8
\)

Add up the two areas \(8+8=16
\)

A is the answer.

I do not see any other possible solution

Not true in the sense we do not have any information about its scale.

The figure could be also this way and the height is perpendicular to the base
