Coplanar: On the same plane. We need to find three points that lie on plane P.
Let's look for the points that lie on plane P. We can see that points A, B, C, and E lie on the plane.
The first and fourth choice has point F, but that point is not on the plane, so those choices are not the correct answer. Also, Point D is not on plane P, so we can get rid of the second choice. Our answer is the third option.
