A Correct answer
Explanation

From Earth, we can see about 59% of the Moon's surface due to a phenomenon called libration - the Moon's wobbling motion as it orbits Earth. Although the Moon is tidally locked (one side always faces Earth), librations cause parts of the far side to become visible at different times, allowing us to see slightly more than half.
