Please help! ASAP An equilateral triangle, △ABC, has been inscribed in ⊙O. Which of the following constructions would result in the regular hexagon inscribed in ⊙O?

A. Three radii are drawn from the center of ⊙O such that each radius forms a 60° angle with each of the other two radii. The points of the radii on the circumference of ⊙O are joined in succession with the vertices of △ABC to form the regular hexagon inscribed within ⊙O.

B. Three diameters are drawn through the center of ⊙O such that each diameter forms a 30° angle with the other two. The points of the diameters on the circumference of ⊙O are joined in succession with the vertices of △ABC to form the regular hexagon inscribed within ⊙O.

C. The arc intercepted by each pair of vertices in △ABC is bisected, and these points are joined in succession with the vertices of the triangle to form the regular hexagon inscribed within ⊙O.

D. Three points are taken on the circumference of ⊙O such that any one point is equally distant from the other two. These points are joined in succession with the vertices of △ABC to form the regular hexagon inscribed within ⊙O.
