Answer:
o A copper-tin alloy
Step-by-step explanation:
- Bronze is composed by copper and tin. This means it is not a pure metal.
- Bronze cannot be mined, so it is not a mineral ore.
- An ionic compound of copper and tin could also be theoretically used to describe a non-solid ionic compound of copper and tin. However bronze is solid.
- Hence the answer is A copper-tin alloy.
