Answer: A. salt, because it's crystalline
Explanation: Since minerals are naturally occurring solids, in addition to being inorganic, then the option with oil is definitely not the answer because oil is liquid. It's also not a lab-grown diamond because it's not grown naturally, although it has a chemical composition which is also a characteristic of minerals. The option with glass is also not the answer even though glass is inorganic, because another definition of minerals is that they have a crystalline structure, so it is a salt. Salt is a mineral.
