(A) The comet rotates around the sun, the lighter mass of the comet is pushed away due to the centrifugal force along
(B) The comet rotates , the lighter mass of the comet is attracted by some star situated in the direction of its tail
(C) The radiation emitted by the sun excites a radial pressure on the comet throwing its tail away from the Sun
(D) The tail of the comet always exist in the same orientation

Correct Answer - Option(A)

Explanation by: Brijesh Goswami

the tail of the comet is always away from the sun because the comet rotates around the Sun the lighter mass of the comet is pushed away due to the centrifugal force alone. the tail of a comet is made up of gas and tiny particles that are carried away from the sun by the solar wind. comets are formed mostly from ice and dust and their tails only form when they are close enough to be melted by the heat from the Sun. As the nucleus of a comet begins to melt it forms a cloud of gas and small particles known as coma when comets travel close enough into the centre of our solar system pressure from sunlight causes the coma to form a tale that stretches away from the Sun.
