(A)-(IV), (B)-(II), (C)-(III), (D)-(I) 
Explanation:

A simple microscope is a magnifying glass that has a double convex lens with a short focal length. Examples of this kind of instrument include the hand lens and reading lens.

Compound Microscope is a microscope with a high resolution and uses two sets of lenses providing a 2-dimensional image of the sample.

Refracting Telescope use lenses to gather more light than the human eye could collect on its own. They focus the light and make distant objects appear brighter, clearer and magnified. This type of telescope is called a refracting telescope.

A reflecting telescope (also called a reflector) is a telescope that uses a single or a combination of curved mirrors that reflect light and form an image.
