Assertion `:` If objective and eye lenses of a microscope are interchanged then it can work as telescope.
Reason `:` The objective of telescope has small focal length.

Answer

D

Explanation

We cannot interchange the objective and eye lenses of a microscope to make a telescope. The reason is that the focal length of, lenses in microscope are very small, of the order of mm or a few cm and the difference `(f_(0)-f_(e))` is very small, while the telescope objective have a very large focal length as compared to eye lens of microscope.
