Your answer is B.
The area of the shaded region will be the area of the circle minus the area of the triangle inside the circle. Then:
The circle has radius 4 cm (distance from the center to the edge of the circle), so the area of the circle is
Now, the area of the triangle is
The base of the triangle is the diameter of the circle (as you can see in the image) and the height is the radius of the circle. Then the are of the triangle is
Finally, the shaded area is = .
