Answer:

The correct options are A, B, C and E

Explanation:

The above speaks to the characteristics of Minerals.

Option D is excluded because minerals cannot be liquid or gaseous. Even if it is possible, those replicated in the laboratory are not considered as minerals neither are minerals liquid. They must be solid. The molecules for most minerals are very tightly or densely arranged because of the nature of their formation. Most of them are formed under consistent and intense pressure.
