The correct Answer is:
To analyze the assertion and reason provided in the question, let's break it down step by step: ### Step 1: Understand the Assertion The assertion states that "Graphite is a non-metal." - Graphite is indeed an allotropic form of carbon, which is classified as a non-metal. Thus, this assertion is true. ### Step 2: Understand the Reason The reason states that "It is the only non-metal which is a good conductor of electricity." - Graphite is unique among non-metals because it can conduct electricity due to the presence of free electrons in its structure. This makes the reason true as well. However, it is important to note that while graphite is a good conductor, it is not the only non-metal that can conduct electricity; other non-metals like certain forms of phosphorous and conducting polymers can also conduct electricity under specific conditions. ### Step 3: Evaluate the Relationship Between Assertion and Reason Now, we need to determine if the reason correctly explains the assertion. - The assertion is about graphite being a non-metal, while the reason discusses its electrical conductivity. Although both statements are true, the reason does not directly explain why graphite is classified as a non-metal. Therefore, while both the assertion and reason are true, the reason is not a correct explanation for the assertion. ### Conclusion The correct evaluation is that both the assertion and reason are true, but the reason does not provide a correct explanation for the assertion. ### Final Answer - **Assertion**: True (Graphite is a non-metal) - **Reason**: True (Graphite is a good conductor of electricity), but it does not explain why graphite is a non-metal.
