Verified step by step guidance

Understand the definition of a mineral: Minerals are naturally occurring, inorganic solids with a definite chemical composition and a crystalline structure.

Identify the key characteristics of minerals: They are inorganic, have a definite chemical composition, and possess a crystalline structure.

Evaluate the given options: Determine which option aligns with the characteristics of minerals.

Option analysis: 'They are organic compounds' is incorrect because minerals are inorganic. 'They are mixtures of different substances' is incorrect because minerals have a definite chemical composition. 'They are liquids at room temperature' is incorrect because minerals are solids.

Conclude that the correct characteristic of minerals is 'They have a definite chemical composition,' which matches the definition and properties of minerals.
