(E) Several days.
(F) One week.
(G) Several weeks.

Correct answer (highlight to unhide): (C)
Earth's rotation causes the moon to rise and to set, and assuming that the moon's revolution around Earth is a much slower rate (a month-long period) compared to Earth's rotation (24-hour period), then the moon will take approximately 12 hours from rise to set.
