Reason: Pollution is not different from contamination.

Options

B. If both assertion and reason are true but reason is not the correct explanation of assertion
C. If assertion is true but reason is false
D. If both assertion and reason are false.

Explanation

To solve the question, we need to analyze both the assertion and the reason provided.

### Step 1: Analyze the Assertion
The assertion states: "Pollution is always caused by human activities."

- **Evaluation**: This statement is incorrect. Pollution can arise from both natural sources (like volcanic eruptions, forest fires, etc.) and human activities (like industrial waste, vehicle emissions, etc.). Therefore, pollution is not exclusively caused by human activities.

### Step 2: Analyze the Reason
The reason states: "Pollution is not different from contamination."

- **Evaluation**: This statement is also incorrect. Pollution refers to the introduction of harmful substances or contaminants into the environment, which can be natural or manmade. Contamination, on the other hand, specifically refers to the presence of harmful organisms or substances that cause disease. Thus, pollution and contamination are distinct concepts.

### Step 3: Conclusion
Since both the assertion and the reason are false, the correct answer is that both the assertion and reason are false.

### Final Answer
Both assertion and reason are false.
