The correct answer is I and II.

  • A comet is made up of ice, dust, and small rocks or particles. They revolve around the sun and can be considered a member of the solar system.
  • When they pass close to the sun they get heated due to solar radiation and start to release gases that are initially in the condensed phase. This release of gases produces a glowing tail behind the comet.
  • When warmed up they produce a bright coma which can be of the order of several times the diameter of Earth.
