The three correct statements about minerals are:
- Minerals are the components that make up rocks.
- Minerals are naturally occurring substances.
- Minerals are made of one element or one compound of elements.
The other statements about observing one property for identification and that minerals can only be identified by color and hardness are misleading, as multiple properties are often used for accurate identification. Furthermore, the statement that rocks are the components that make up minerals is incorrect; it's the other way around.
