The answer is c
1/6 divided by 1/2
i had this question on my own
There is two possible conic section that can be formed when the plane intersects the vertical axis, a circle, and an ellipse. Cutting one nappe of double napped cone perpendicular to the vertical axis means the cut is straight across the cone making a right angle. The conic section formed would be a circle.
It's impossible for 2 factors of 12 to add up to 16. So there would be no answer to that.
