C Correct answer
Explanation

Neptune was long credited with 13 moons in many textbooks before the discovery of its 14th moon, Hippocamp, in 2013. Mars has only 2 moons (Phobos and Deimos), and Saturn has over 80. In the context of older GK questions, Neptune is the intended answer for having 13 moons.
