Other options are not correct: a reserve refers to the amount of a mineral that can be economically extracted from a deposit, tailings are the waste materials from mining operations, and a resource refers to any naturally occurring material that has the potential to be extracted and used for economic purposes, including metals but also non-metallic materials like coal or oil.
