Quizplus · Accepted Answer

The Oort cloud is a vast spherical shell surrounding the Solar System that extends from about 2,000 to 100,000 astronomical units (AU) from the Sun. It is believed to contain billions of icy objects, including comets. These comets were likely formed closer to the Sun and were flung out into the outer reaches of the Solar System by gravitational interactions with the giant planets. Some were also perturbed by passing stars or other galactic influences. The other options are unlikely as there is no evidence to support them.
