comet tail
D
none of the above
Explanation: 

Detailed explanation-1: -Most comets actually have 2 tails: a plasma tail made of ionized gas, and a dust tail made of small solid particles.

Detailed explanation-2: -Generally, a comet has two tails; the blue plasma tail and the red dust tail (or Type 1 (ion) tail and Type 2 (dust) tail). The plasma tail is caused by an interaction between the solar wind and the cometary plasma, while the dust tail is by the solar radiation pressure to the cometary dust.

Detailed explanation-3: -The tail of dust is left behind in the comet’s orbit in such a manner that it often forms a curved tail called the antitail, only when it seems that it is directed towards the Sun.

Detailed explanation-4: -properties of comets The dust tail forms from those dust particles and is blown back by solar radiation pressure to form a long curving tail that is typically white or yellow in colour.

Detailed explanation-5: -Comets have two main tails, a dust tail and a plasma tail. The dust tail appears whitish-yellow because it is made up of tiny particles-about the size of particles of smoke-that reflect sunlight. Dust tails are typically between 1 and 10 million kilometers (about 600, 000 to 6 million miles) long.
