GPT-4o mini · Answer

C. No, coal is not a mineral because coal is made up of dead plants.

Coal is classified as a sedimentary rock rather than a mineral. It is formed from the remains of ancient plant material that has been subjected to heat and pressure over millions of years. While minerals are defined as naturally occurring inorganic solids with a specific chemical composition and crystalline structure, coal does not fit this definition because it is organic in origin.
