Detailed Solution

If a new planet is discovered between Uranus and Neptune, the time period of the new planet would be less than that of Neptune.
The orbital time period is the time taken for a given object to make one complete orbit around another object. In this case, when a new planet is introduced between Uranus and Neptune, the distance between the Sun and the new planet is lesser than the distance between the planet Neptune and the Sun. Also, the distance between the Sun and the new planet is more than the distance between the planet Uranus and the Sun. Hence, the time period of the new planet is lesser than the time period of Neptune is the correct option among the four options given.
