A Correct answer
Explanation

Water is very essential for all life processes on earth. Water is continuously being recycled by the processes of evaporation, condensation to form clouds, precipitation to form rain. Thus water once evaporated again gets recycled on the earth's surface in the form of rain; therefore the ultimate source of water in earth is rain.
