Final answer:
The body component of a microscope typically comprises the eyepiece and objective lenses, both of which are essential for magnification in a compound microscope.
Step-by-step explanation:
The body component of a microscope typically comprises the eyepiece and objective lenses. These are integral parts of a compound microscope, which is a multiple-element system with more than a single lens. The objective lens is the first lens that captures the object and magnifies it to create a first image—a case 1 image that is larger than the object itself. This image then acts as the object for the second lens, the eyepiece, which forms a case 2 final image, further magnified for the viewer. Both lenses are crucial for the function of the microscope, contributing to its overall magnification capability (m = mobj * meye). In conclusion, the correct answer to the student's question about what comprises the body component of a microscope is B. Eyepiece and objective lenses.
