Answer:
D. binocular compound light microscope
Explanation:
The most appropriate microscope for this research is the binocular composite light microscope, because these types of microscope work by capturing light in a tiny, well-lit area without the need for a large lens. The lens of a microscope is small and spherical, so the image of the object is focused a short distance from the microscope tube. The image is then magnified by a second lens that brings it into the viewer's field of view. Making it possible to view bodies as small as the research mite.
