When a comet is farthest from the Sun in its orbit, then its NUCLEUS is present for more time (Option c).

  • The comet's nucleus is the solid and frozen core of a comet, which consists of solid rocks, water (H2O) ice, and frozen gases (e.g., carbon monoxide, carbon dioxide, methane, etc).

  • When the comet's nucleus is warmed by the heat from Sun, then it releases gas and dust and thereby generates the comet's coma.

  • Most comets have a nucleus that is typically 1 to 10 kilometers (km) in size.

In conclusion, when a comet is farthest from the Sun in its orbit, then its NUCLEUS is present for more time (Option c).
