B Correct answer
Explanation

The Moon's sidereal orbital period (time to complete one orbit relative to the stars) is 27.3 days. This is different from the synodic month (29.5 days, new moon to new moon) which includes Earth's own movement around the Sun. The 27.3-day figure is the true orbital period.
