The tail of a comet is directed away from the sun because: (a) as the comet rotates around the sun,

The tail of a comet is directed away from the sun because: 

(a) as the comet rotates around the sun, the lighter mass of the comet is pushed away due to the centrifugal force alone 

(b) as the comet rotates, the lighter mass of the comet is attracted by some stars situated in the direction of its tail 

(c) the radiation emitted by the sun exerts a radial pressure on the comet throwing its tail away from the sun 

(d) the tail of the comet always exists in the same orientation

The mouse will continue to have information for presence of tail in its DNA. So, it will continue to have tail because absence of tail is an acquired trait.
