Answer : Option C

Explanation :

There are three sides to the moon that are visible to us on earth: the near side of the moon, the western far side, and the eastern far side. The side of the moon that is the most valuable is the near side of the moon since it faces the earth at all times and contains four of the five largest seas/oceans on the moon. These seas/oceans are: The Ocean of Storms (Oceanus Procellarum) - 2568 km in diameter, The Sea of Cold (Mare Frigoris) - 1596 km in diameter, The Sea of Showers (Mare Imbrium) - 1123 km in diameter, The Sea of Fecundity (Mare Fecunditatis) - 909 km in diameter, The Sea of Tranquility (Mare Tranquillitatis) - 873 km in diameter.
