Answer : Option C
Explanation :
The Moon is showing its same face to the Earth because Its periods of rotation and revolution are the same. The moon keeps the same face pointing towards the Earth because its rate of spin is tidally locked so that it is synchronized with its rate of revolution (the time needed to complete one orbit). In other words, the moon rotates exactly once every time it circles the Earth.
