Depends on the magnification you are looking for... usually, a light microscope is enough (1000x max magnification)...
An electron microscope is powered by high energy beams and can magnify many times higher than the light microscope (where magnification is limited by the wavelength of light). The magnification of an EM is on the nano scale.
(P.S.: as a chemist, I'd always choose an EM over an optical microscope as I can always zoom in or out depending on my needs) ;)
Answer: Option B
Explanation:
The population of the moth is mixed with light colored and dark colored moth but the population of light colored moth is more as compared to that of the dark colored moth.
The light colored moth get mixed in the population of the lichen as they are also of light colored.
The population of the light colored moth will increase as they will be preyed less because of the color that matches to its surrounding.
