A. Somewhere outside the solar system
B. Oort's cloud
C. The ecliptic plane
D. The asteroid belt
E. The Kuiper belt

Answer 1

Comets are divided into two types. Long-period comets are the comets that take more than two hundred years to finish an orbit throughout the Sun originate from the Oort Cloud.

Explanation:

• The Oort Cloud has sufficient distance apart of the Sun than the Kuiper Belt, it seems that the Oort Cloud objects were made closer to the Sun than the Kuiper Belt things.
• Long-period comets have highly eccentric orbits.
• The Oort cloud is considered to own a large range commencing from among 2,000 and 5,000 AU to 50,000 AU.
• The chemical makeup of long-period and short-period comets is quite alike.
