Solution

The correct option is A Both A and R are correct and R explains A
Water is usually polluted with microscopic impurities. The clear appearance of water does not make it potable. Several chemical indications such as pH, salt content and dissolved oxygen determine if the water is potable and fit for human consumption. All these can be tested through chemical analysis. A simple physical examination by looking at the water does not determine the potability of water.
