Assertion (A): A solar cooker cooks the meal due to green house effect.
Reason (R): The plane mirror is responsible for producing the green house effect.

Options

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

Explanation

**Step-by-Step Solution:**

1. **Understanding the Assertion (A):**
The assertion states that "A solar cooker cooks the meal due to greenhouse effect." This is correct. A solar cooker utilizes the greenhouse effect to trap heat and cook food.

2. **Functioning of a Solar Cooker:**
A solar cooker typically consists of a black-colored box with a transparent lid. The black surface absorbs sunlight, and the transparent lid allows sunlight to enter while trapping heat inside.

3. **Role of Greenhouse Gases:**
In the context of a solar cooker, the air inside can be considered as containing greenhouse gases. These gases trap the heat that enters the cooker, preventing it from escaping. This leads to an increase in temperature inside the cooker, which cooks the food.

4. **Understanding the Reason (R):**
The reason states that "The plane mirror is responsible for producing the greenhouse effect." This is incorrect. The greenhouse effect is primarily caused by greenhouse gases, not by mirrors.

5. **Role of the Plane Mirror:**
The plane mirror in a solar cooker is used to reflect sunlight towards the black box. It helps in directing the sunlight but does not contribute to the greenhouse effect itself.

6. **Conclusion:**
Therefore, the assertion is true, while the reason is false. The correct answer is that Assertion (A) is true, and Reason (R) is false.

**Final Answer:**
Assertion (A) is true, and Reason (R) is false.
