○ a. sodium
○ b. magnesium
○ c. carbon

Explanation:

Diamond and graphite are allotropes of carbon, and coal is mostly composed of carbon (along with other impurities). Sodium (A) and Magnesium (B) are metals, not nonmetals. Oxygen (D) is a nonmetal but is not the main component of diamond, graphite, or coal. So the correct answer is Carbon.

Answer:

C. Carbon
