The sidereal period of the Moon is the time it takes for the Moon to orbit the Earth once with respect to the stars. This is about 27.3 Earth days. Unlike the synodic period (choice A), which is the time it takes for the Moon to return to the same phase (e.g. full Moon to full Moon), the sidereal period is based on the position of the Moon relative to the stars.
