    We can combine the convex and concave lenses, and the resulting lens is known as a convexo-concave or concavo-convex lens, with one side convex and the other side concave. Because convex and concave lenses are three-dimensional objects because they are formed from two spheres (three-dimensional objects), the combined object is also three-dimensional. So the option which suits the most is The surface of the object may be concave in some places and convex in other places. (C) is correct.
