In our solar system, the region near Neptune and beyond is known as :

  • A.Kuiper belt
  • B.Kepler’s belt
  • C.Planetary ocean
  • D.Oort nebula

Answer: A

The region near Neptune and beyond is the Kuiper belt.

The Kuiper belt is a disc of icy bodies, remnants of planet formation, extending from about Neptune's orbit (30 astronomical units) to about 50 astronomical units from the Sun. Pluto, Eris and many other dwarf planets and short-period comets belong to it or to its scattered disc.

The Oort cloud (not 'Oort nebula') is a far more distant spherical shell of comets, thousands of astronomical units away. There is no 'Kepler's belt', and 'planetary ocean' is not a region of the solar system.
