Answer
A single biconvex lens
Reason — A Simple microscope consists of a single biconvex (convex) lens which produces a magnified image of an object. Two convex lenses are used in a compound microscope. A biconcave lens and two concave lenses diverge light rays and do not produce the magnified image required in a simple microscope..
