The correct Answer is:
To solve the question, we need to analyze both the assertion and the reason provided. ### Step 1: Analyze the Assertion The assertion states: "Wood is a bad conductor of electricity." - This statement is **true**. Wood is indeed considered a poor conductor of electricity, which is why it is often used as an insulator in various applications. ### Step 2: Analyze the Reason The reason states: "Wood has a large number of free electrons." - This statement is **false**. Wood does not have a large number of free electrons. In fact, it has very few free electrons, which is one of the reasons it is a poor conductor of electricity. Good conductors, like metals, have a high density of free electrons that allow electrical current to flow easily. ### Step 3: Conclusion Since the assertion is true and the reason is false, we can conclude that: - The correct option is that the assertion is true, but the reason is false. ### Final Answer The assertion is true, but the reason is false. ---
