B. by indicating if there is too much sediment in the water

C. by indicating whether the water is too acidic or basic

D. by indicating if there is enough dissolved oxygen in the water

The correct answer is - C. by indicating whether the water is too acidic or basic.

Explanation:

pH meter or pH scale is the color indicating scale to measure the acidity or basicity of the particular solution of the element. pH meter measures the hydrogen ion activity of the freshwater or saline water of the hydrosphere and if it is acidic or basic. It helps in determining if the water can be a drink or if the water body has an appropriate pH level for the organisms to live.

Thus, the correct answer is - C.
