To find the area of the polyhedron, we find the area of all faces of the polyhedron or the area covered by the net of the polyhedron
Considering all the options the lateral surface area is the area of the polyhedron without the area of the base. Therefore the surface area of a polyhedron can also be defined as the lateral surface area which is the area of every other face of the polyhedron except the base and then adding it to the area of one of the bases.
so option C
