Solution

The correct option is C Is less than the focal length of eyepiece lens
As the magnifying power of compound microscope is inversely proportional to the focal length of the objective lens.
Hence , smaller is the focal length, higher is the magnifying power.
Therefore, focal length of objective lens is less than the focal length of eyepiece lens.
