The correct answer is:
If both the assertion and reason are true and reason is a correct explanation of the assertion.
Time-period of simple pendulum, $T=2 \pi \sqrt{\frac{l}{g}}$
Thus time-period is inversely proportional to $\sqrt{g}$ (where $g$ is acceleration due to gravity). And as the value of $g$ on a satellite is zero, therefore time-period of pendulum is infinity.
