Isn't the answer "E"? Please tell me!
The coverslip ensures both your specimen and the objective of the magnifying lens from harm. Dampness will demolish the seal around the edge of the focal point (lens) unless a focal point is uncommonly made to focus through water or oil. Numerous of the focal points are made with the refractive index of a coverslip figured into where their central point is, so indeed in the event that you fair need to damp mount something, you still require a coverslip on it. It too, keeps the specimen from drying out by anticipating dissipation when uncovered to the warm of the light on the scope.
Glad to help ya!! :)
