D . 400X

View Answer

Answer: D

Explanation:

When using a microscope, the total magnification is calculated by multiplying the magnification power of the ocular lens (eyepiece) by the magnification power of the objective lens. In this case, a 10X ocular lens combined with a 40X objective lens results in a total magnification of 400X (10X * 40X = 400X).
