Correct Answer
Correct Answer

Option D is the correct answer.

Detailed Explanation

A pollutant is a substance or energy introduced into the environment that has undesired effects, or adversely affects the usefulness of a resource. Water is not inherently a pollutant; it is a vital resource. However, water can become a pollutant if it is contaminated or in the wrong place (e.g., floodwater). In its natural state, it is not considered a pollutant.
