Both Assertion and Reason are true, and the Reason is the correct explanation for the Assertion. The assertion is true that graphite is used as a lubricant in machines. This is because the layers of graphite can slide over each other easily due to weak van der Waals forces between them. The reason provided for the assertion is also true, and it is the correct explanation for why graphite is used as a lubricant. The weak van der Waals forces allow the layers to slide past each other with minimal friction, making it an excellent lubricant.
Hence option A is the correct answer.
Option (B) is incorrect because it incorrectly states that the assertion is correct but the reason is incorrect. Both the assertion and reason are correct. Hence option B is incorrect.
Option (C) is incorrect because it incorrectly states that the assertion is incorrect but the reason is correct. The assertion is correct, and the reason is also correct. Hence option C is incorrect.
Option (D) is incorrect because it incorrectly states that both the assertion and reason are incorrect. Both the assertion and reason are correct. Hence option D is incorrect.
