Answer : Option B
Explanation :
Comets are celestial bodies moving about the solar system in Elliptical orbits usually accompanied by a long shining tail. A comet is an icy, small Solar System body that, when passing close to the Sun, warms and begins to release gases, a process called outgassing. This produces a visible atmosphere or coma, and sometimes also a tail. These phenomena are due to the effects of solar radiation and the solar wind acting upon the nucleus of the comet.
