Viruse is a micro organism which can not be seen with ordinary microscope accept with the help of electron microscope and it's the cause of most chronic disease
viruses re smaller dan bacteria whilst viruses re larger...they can only be seen by a microscope with more advanced modification called d electron microscope
While I agree that a virus cannot be seen with an ordinary light microscope (option "C"), I must point out that viruses are not microrganisms by technically difining organisms. Only objects which are living or those which once possesed life in them can be reffered to as organisms.
