Solution

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
Transmission electron microscopy (TEM) is a type of microscopy, which is used to see the fine structural details within the cell. Objects as small as 0.1 nm may be observed with help of it.
Ultra-thin sections of the object must be prepared because electrons can penetrate matter only a short distance. The resolving power of electron microscope is 10 A which is 100 times more than the light electroscopy. Study of living things can not be done through this microscope, because of high voltage, which is required to operate it, kills the cells.
