Why can acid rain water be harmful for aquatic organisms?

Answer and explanation

Correct answer: It lowers the pH of water

Acid rain contains acidic substances formed when pollutants such as sulfur and nitrogen oxides react in the atmosphere. When this rain enters lakes, rivers, or ponds, it can lower their pH. Many aquatic organisms and their eggs require a limited pH range, so excessive acidity can disturb survival, reproduction, and mineral balance. Thus option A gives the correct general reason; the other claims are absolute or chemically incorrect.
