B Correct answer
Explanation

To find the total magnification of a microscope, you multiply the magnification of the eyepiece by the magnification of the objective lens. Multiplying 10 by 40 gives a total magnification of 400x. Adding the magnifications together is a common mistake that leads to the incorrect answer of 50x.
