Question

which part of the light microscope is the arrow pointing to? light source objective lens coarse adjustment stage

Explanation:

The arrow in the light microscope image points to the objective lens. The objective lens is the part of the microscope that is close to the specimen on the stage and is used for magnifying the specimen. The light source is at the base, coarse adjustment is a knob, and the stage holds the specimen, so the correct identification is the objective lens.

Answer:

B. objective lens (assuming the options are labeled with letters, but based on the text, the correct option is the one with "objective lens")
