Answer;
A. exist naturally
Minerals are solid, inorganic substances that exist naturally.
Explanation;
A mineral is a naturally occurring inorganic solid, with a definite chemical composition, and an ordered atomic arrangement.
Minerals are naturally occurring; they are not made by humans.
Minerals are inorganic; they have never been alive and are not made up from plants or animals.
Minerals are solids; they are not liquids (like water), or gases (like the air around you).
Minerals have a definite chemical composition; each one is made of a particular mix of chemical elements.
Minerals have an ordered atomic arrangement; the chemical elements that make up each mineral are arranged in a particular way - this is why minerals 'grow' as crystals.
