The correct option is D Hexagonal pyramid A net is a 2-dimensional shape that can be folded to form a 3-dimensional shape or a solid. Make sure that the solid and the net have the same number of faces and that the shapes of the faces of the solid match the shapes of the corresponding faces in the net. The given net has 7 faces. The net is to be folded to form the solid and make sure that all the sides fit together properly. Now, we observe that one of the side has 6 sides so it will be a hexagon and other 6 faces are traingles meeting at one point. So, this is the net of a Hexagonal pyramid.
