Correct Answer: Option C
Explanation

Diamond is the hardest form of carbon. It's also the hardest naturally occurring substance on Earth. Diamond is an allotrope of carbon, meaning it's a variation of carbon's structure. In diamond, carbon atoms are arranged in a tetrahedral structure, with each carbon atom bonded to four other carbon atoms. This structure creates a rigid, three-dimensional network of carbon atoms. Thus,the strong bonds between the carbon atoms make diamond extremely hard.
