| B. | Lake water |
| C. | River water |
| D. | Sea water |
| Answer» A. Rain water | |
|
Explanation: Rainwater is often considered the purest form of water available on the Earth. The evaporation of water by the sun allows the salts and other impurities to be left behind out of the water. However, in reality, rain water is often much less than pure when it reaches the surface of the Earth due to the high pollution of air with toxic gases. |
