Neptune: The size of this planet is the smallest of all the outer planets. The rotational period of this planet is 16 hrs 6 min and its atmosphere is made up of Methane gas.
Order of size of the planets: Jupiter > Saturn > Uranus > Neptune
Order of rotation period of the planets: Uranus > Neptune > Saturn > Jupiter.
Jupiter has the fastest and Uranus has the slowest rotation.
Hence, the answer to this question is Option C.
