The word "comet" comes from an ancient word that means "tail on the body." This is because comets are known for their bright tails that can be seen trailing behind them as they move through space.
The correct answer is:
C) tail on the body.
Comets have long tails composed of dust and gases that are illuminated by the sun, creating a spectacular sight in the night sky. The ancient word associated with comets reflects this distinctive feature of comets, which sets them apart from other celestial bodies like stars or planets.
