These question consists of two statements each printed as Assertion and Reason. While answering these question you are required to choose any one of the following four responses.
Assertion: Good conductors of electricity are also good conductors of heat
Reason: In good conductors of electricity, there are large numbers of free electrons.

Options

A. If both Assertion and Reason are correct and Reason is also a good absorber of radiation at a given wavelength.
B. If both Assertion and Reason are correct but Reason is not the correct explanation of Assertion.
C. If Assertion is true but Reason is false
D. If Assertion is false but Reason is true.

Explanation

To solve the given question, we need to analyze both the Assertion and the Reason provided.

### Step 1: Analyze the Assertion
The assertion states: "Good conductors of electricity are also good conductors of heat."
- This statement is true. Good conductors of electricity, such as metals, are also good conductors of heat. This is because the same free electrons that facilitate the flow of electric current also enable the transfer of thermal energy.

### Step 2: Analyze the Reason
The reason states: "In good conductors of electricity, there are large numbers of free electrons."
- This statement is also true. In metals, there are indeed a large number of free electrons that can move freely, allowing both electrical and thermal conductivity.

### Step 3: Determine the Relationship Between Assertion and Reason
Now we need to determine if the Reason correctly explains the Assertion:
- Since the presence of free electrons is the underlying reason why good conductors of electricity are also good conductors of heat, the Reason supports the Assertion.

### Conclusion
Both the Assertion and Reason are true, and the Reason is the correct explanation of the Assertion. Therefore, the correct response is:
- Both Assertion and Reason are correct, and Reason is the correct explanation of Assertion.

### Final Answer
The correct option is: Both Assertion and Reason are correct, and Reason is the correct explanation of Assertion.
