A: Global warming is due to Green House Effect.
R: Only Green House gas is `CH_(4)`

Options

A. If both Assertion & Reason are true and the reason is the correct explanation of the assertion, then mark (1).
B. If both Assertion & Reason are true but the reason is not the correct explanation of the assertion, then mark (2)
C. If Assertion is true statement but Reason is false, then mark (3)
D. If both Assertion and Reason are false statements, then mark (4).

Answer

To analyze the given statements, we need to evaluate both the assertion (A) and the reason (R) provided in the question.

### Step 1: Understand the Assertion
The assertion states that "Global warming is due to Green House Effect."
- The greenhouse effect refers to the process by which certain gases in the Earth's atmosphere trap heat, preventing it from escaping back into space. This leads to an increase in the Earth's average temperature, which is commonly referred to as global warming.

### Step 2: Understand the Reason
The reason states that "Only Green House gas is CH₄ (methane)."
- This statement is incorrect. While methane (CH₄) is indeed a greenhouse gas, it is not the only one. Other significant greenhouse gases include carbon dioxide (CO₂), nitrous oxide (N₂O), water vapor (H₂O), ozone (O₃), and fluorinated gases.

### Step 3: Evaluate the Truth of Each Statement
- The assertion (A) is true because global warming is indeed caused by the greenhouse effect.
- The reason (R) is false because it incorrectly claims that CH₄ is the only greenhouse gas.

### Step 4: Conclusion
Since the assertion is true and the reason is false, we conclude that:
- The assertion is correct, but the reason does not correctly explain the assertion.

### Final Answer
The correct evaluation is that the assertion is true, while the reason is false.
