The mass and the diameter of a planet are three times the respective values for the Earth. The period of oscillation of a simple pendulum on the Earth is \( 2 s \). The period of oscillation of the same pendulum on the planet would be

(a) \( \frac{3}{2} s \)
(b) \( \frac{2}{\sqrt{3}} s \)
(c) \( \frac{\sqrt{3}}{2} s \)
(d) \( 2 \sqrt{3} s \)
