A
The Moon is tidally locked to Earth (its rotation period equals its orbital period), so the same hemisphere always faces Earth — hence only one face is normally visible. The other choices describe effects of the Moon’s orbital motion (B and C) or Earth’s rotation (D), not its synchronous rotation.
