Answer:

Electron microscope would be used for if,

C) details of cell structures needed to be distinguished.

Step-by-step explanation:

  • The general principal of electron microscopy is analogous to light microscopy except that it uses electrons to analyse the specimen instead of light.
  • Electron microscopy focuses a beam of electron on the target sample and records the difference in absorption by different surfaces.
  • Electron microscopy is used to get the detailed structure of cells and surface features of various viruses and bacteria.
  • However, it is not possible to view living biological samples through electron microscope because high velocity electron have immense energy to kill living cells.
  • These samples are thus, fixed and then viewed.
