B Correct answer
Explanation

In a compound microscope, both the objective and the eyepiece have short focal lengths to maximize magnification. However, the focal length of the objective (f_o) is typically smaller than the focal length of the eyepiece (f_e) to ensure the first image is formed within the eyepiece's focal range.
