A Correct answer
Explanation

A simple microscope consists of a short focus convex lens because shorter focal length provides higher magnification. The convex lens converges light rays from the object, creating a magnified virtual image when the object is placed within the focal length. A concave lens always produces diminished images, and long focal length would give lower magnification.
