  (b){\text{ cold}} \\
  (c){\text{ outer}} \\
  (d){\text{ dwarf}} \\

Answer 1

- Hint – There is a belt present between the orbits of two planets namely Mars and Jupiter. All the planets before the belt or inside the belt are termed as inner planets and all the planets outside of this belt are the outer planets. Use this concept to figure out that the given planet lies to the interior of the belt or to the exterior of it.

Complete step-by-step solution -

A belt of asteroids is present between the orbits of Mars and Jupiter.
This belt separates the planets into inner planets and outer planets.
The planets before the belt of asteroids are called inner planets (Mercury, Venus, Earth and Mars)
And the ones outside are called outer planets.
Therefore, Jupiter, Saturn, Uranus and Neptune are called outer planets.
So this is the required answer.
Hence option (C) is the correct answer.

Note – The asteroid belt is a torus-shaped region in the solar-system. This belt is occupied by a great many solids, irregularly shaped bodies of many sizes. The main Asteroid belt lies more than two-and-a-half times as far as Earth does from the sun. Jupiter's gravity has a huge impact over this asteroid belt.
