A Correct answer
Explanation

Graphite has a layered structure with weak van der Waals forces between layers, making it slippery to touch. Its delocalized electrons within each layer allow graphite to conduct electricity well, unlike diamond which has no free electrons. While graphite is grayish-black, option C is incorrect because it's actually a good conductor, not a bad one.
