Which one of the following options correctly states two major differences between a simple microscope and a compound microscope?
a) Simple microscope uses two converging lenses and generally provides magnification above 100; compound microscope uses one converging lens and provides magnification below 10.
b) Simple microscope uses a diverging lens placed close to the eye, whereas a compound microscope uses a converging objective and a diverging eyepiece.
c) Simple microscope uses one converging lens and normally produces an inverted virtual image; compound microscope uses two converging lenses and produces an erect final image.
d) Simple microscope uses one converging lens and generally provides magnification below 10; compound microscope uses two converging lenses and can achieve magnification well above 100.
