Correct option is C)

 
A basic microscope can also be made with a convex lens. 
A virtual, erect, and magnified image is generated by keeping the object between the focal length and the mirror. 
A shorter focal length provides greater power and allows for higher magnification. 
As a result, a convex lens with a focal length of 5 cm is preferred.
