Although Neptune is the farthest planet from the Sun, it travels in a fixed orbit around the Sun and never changes its path. What is the reason for this?
A) The magnetic pull of the Sun holds Neptune in its orbit.
B) The gravitational pull of the Sun holds Neptune in its orbit.
C) The nuclear force acting between the Sun and Neptune holds the latter in its orbit.
D) The repulsive force of bodies outside the solar system holds Neptune in its orbit.

Whether a farthest planet or a nearest planet, all the planets in the solar system are held in their respective orbits by the mutual gravitational force of attraction. That is, the Sun exerts a gravitational force on the planet and the planet in turn pulls the Sun towards it. These two forces are equal in magnitude and oppositely directed to each other.

That is very well explained by the Newton's universal gravitational law,

As the distance between the Sun and the planet increases, the mutual gravitational force of attraction between the planets will decrease.

Mercury, Venus, Earth , Mars, Jupiter, Saturn, Neptune and Uranus are the planets that belong to the solar system. All these planets are revolving around the Sun.
