The intersection of a right cylinder and a plane makes an oval cross section. Which option is true about the plane of intersection?

The right cylinder is cut with a plane parallel to the base.

The right cylinder is cut with a plane perpendicular to the base and passing through the center.

The right cylinder is cut with a plane perpendicular to the base but not passing through the center.

The right cylinder is cut with a plane that is neither parallel nor perpendicular to the base.

Look at the attached set of images, some of which are cross sections of right circular cylinders. I think what is there will help you decide on an answer.
