If the equilateral triangle formed were on the plane (i.e. a flat triangle), then A would be the answer. However, the triangle here encloses a portion of the surface area of a sphere. Since there is a bulge in the area, the area will be a little more than the area of a flat equilateral triangle.hardik.jadeja wrote:OA is D but don't think its right. I think it should be A

That said, I think this question is out of scope. I've certainly never seen a an official GMAT question related to the surface area of a sphere before.
