The base of a cube is parallel to the horizon. A plane cuts through the cube creating a pentagon-shaped cross section. Which kind of plane could it be? A. a vertical plane cutting two adjacent edges of the base

Ba vertical plane cutting two opposite edges of the base
Ca slanting plane cutting two adjacent edges of the base
Da slanting plane containing exactly one edge of the cube

Verified Answer :

I think the answer is C. a slanting plane cutting two adjacent edges of the base. I thought of the Pentagon building in Washington where it also has a pentagon-shaped cross section. 

Answer:

C. a slanting plane cutting two adjacent edges of the base

Step-by-step explanation:

The base of a cube is parallel to the horizon. A plane cuts through the cube creating a pentagon-shaped cross section. The plane could be - a slanting plane cutting two adjacent edges of the base.
