A)because the other face points toward us only at new Moon,when we can't see the Moon
B)because the Moon does not rotate
C)because the Moon's rotational and orbital periods are equal

The Moon's rotational period (the time it takes to rotate once on its own axis) is equal to its orbital period (the time it takes to orbit around Earth), resulting in the same face of the Moon always being visible from Earth. This is called synchronous rotation.
