Why must an electron microscope be used to observe the cristae of a mitochondrion?
- AThe magnification of the electron microscope is greater than that of the light microscope.
- BThe membranes of the cristae are separated by a distance greater than $200\,\text{nm}$.
- CThe maximum resolution of a microscope using visible light is too low.
- DThe wavelength of an electron beam is longer than the wavelength of visible light.
