Which of the following is NOT a standard part of a light microscope?

Explanation:
The thing being tested is distinguishing parts of the microscope from features of the specimen. A light microscope includes hardware like stage clips to keep the slide steady, a diaphragm to control the illumination, and a coarse adjustment knob to bring the specimen into rough focus. The nucleus, on the other hand, is a cellular structure found inside the cells you’re viewing, not a component of the microscope itself. So it’s not a standard part of the instrument, whereas the other items are.
