Assertion (A) Green house effect was observed in houses used to grow plants and these are made of green glass.
Reason (R) Green house name has been given because glass houses are made of green glass.

Options

A. Both A and R are correct and R is the correct explanation of A
B. Both A and R are correct and R is not the correct explanation of A
C. Both A and R are not correct
D. A is not correct but R is correct

Explanation

**Step-by-Step Solution:**

1. **Understanding the Assertion:**
- The assertion states that the greenhouse effect is observed in houses used to grow plants, which are made of green glass.
- A greenhouse is indeed a structure designed to cultivate plants by providing a controlled environment.

2. **Explaining the Greenhouse Effect:**
- The greenhouse effect occurs when sunlight enters the greenhouse and is absorbed by the plants and surfaces inside.
- The heat energy from the sun is then trapped inside, preventing it from escaping, which helps maintain a warm temperature suitable for plant growth.

3. **Understanding the Reason:**
- The reason provided states that the term "greenhouse" is derived from the fact that these houses are made of green glass.
- While it is true that greenhouses can be made of green glass, the term "greenhouse" actually refers to the function of the structure rather than the color of the glass.

4. **Evaluating the Assertion and Reason:**
- Both the assertion and reason are correct statements. The assertion correctly describes the purpose of a greenhouse, and the reason correctly identifies that greenhouses can be made of green glass.
- However, the reason does not fully explain why the structure is called a greenhouse, as the name is more about the function of the house in growing plants rather than the color of the glass.

5. **Conclusion:**
- Therefore, both the assertion and reason are correct, but the reason is not a correct explanation of the assertion. The correct answer is that both statements are true, but the reason does not adequately explain the assertion.

**Final Answer:**
- Both Assertion (A) and Reason (R) are correct, but R is not the correct explanation of A.
