Magnification of the microscope = Magnification of objective lens x Magnification of ocular lens

Given that the magnification of ocular lens = 10x and the magnification of the microscope = 400x

Therefore, Magnification of objective lens = Magnification of microscope / Magnification of ocular lens = 400/10 = 40x.

Hence, the answer is choice B) 40x.
