Two statements are given below and they are labelled as

Solution

Assertion (A): Graphite is used in the designing of carbon paper. Reason (R): Graphite is a good conductor of electricity. The assertion (A) is correct. Graphite is indeed used in the design of carbon paper. Graphite's unique properties, such as its ability to leave a mark on paper and its smooth, slippery texture, make it suitable for this application. The reason (R) is also correct. Graphite is a good conductor of electricity due to its unique structure where carbon atoms are arranged in layers. The delocalized electrons between these layers allow for the conduction of electricity. Both the assertion and reason are accurate, and the reason provides a relevant explanation for why graphite is used in designing carbon paper. Therefore, the correct answer is that the assertion (A) is true, and the reason (R) is the correct explanation of the assertion.
