A light microscope would be most advantageous for viewing which of the following? a. small molecule such as water b. a DNA strand c. virus d. eukaryotic cells such as green algae

D

Explanation:

The resolution of a light microscope is approximately 200 nanometers due to the wavelength of light. A eukaryotic cell is approximately 1 - 5 micrometers. This means that light can be used to view a eukaryotic cell because the wavelength of light is smaller than the size of the cell. The other options are of a smaller size than the light wavelength and hence lower wavelength beams (such as those of electron microscope) or laser can be used to view them.
