Which statement concerning a light microscope is correct?
- AAs the distance to see two points as separate points decreases, the resolution also decreases.
- BA bacterium $0.2\,\mu\text{m}$ in diameter will not be visible if the resolution is $220\,\text{nm}$.
- CTwo membranes that are less than $300\,\text{nm}$ apart will be visible as two separate membranes if the wavelength of light is $600\,\text{nm}$.
- DThe resolution will improve with visible light of a longer wavelength, such as red light.
