Quizplus · Accepted Answer

The Oort Cloud is the correct answer because it is a theoretical cloud of predominantly icy planetesimals proposed to surround the Sun at distances ranging from 2,000 to 200,000 AU. It is believed to be the source of long-period comets, thus explaining the spherical distribution of cometary nuclei similar to the distribution of globular clusters in the Halo.
