Which of the following statements correctly describes the magnification of the PCM eyepiece?

Explanation:
The main idea is that magnification from a microscope comes from the eyepiece, the ocular lens, which multiplies the image formed by the objective. The PCM eyepiece is specified as 10x, so looking through it makes the image appear ten times larger than it does to the eye without magnification. The total magnification you see in use would be this 10x multiplied by whatever objective you have installed (for example, a 40x objective would give 400x total). Other magnifications (5x, 15x, 20x) would come from different eyepieces, but the PCM eyepiece in this context is 10x, which is why that option is the correct one.
