correct answer is C 1)Tail of the comet always faces away from the sun. 2)As the comet moves away from the sun,the solar heating diminishes.As a result,coma and nucleus of the comet disappear.When it is at the position farthest from the sun,nucleus warms and begins to sublimate and its size becomes smaller than its previous size.
