## Step 1<br />The problem is asking us to identify a naturally occurring inorganic solid that has a specific chemical composition and a definite crystalline structure. The options provided are magma, rock, and mineral.<br /><br />## Step 2<br />Let's analyze each option:<br /><br />- Magma: Magma is a molten or semi-molten natural material from which all igneous rocks are formed. It is not a solid, so it does not meet the criteria of the problem.<br /><br />- Rock: Rocks are solid natural masses of minerals. They can be organic or inorganic, and they do not necessarily have a specific chemical composition or a definite crystalline structure.<br /><br />- Mineral: A mineral is a naturally occurring inorganic solid with a definite chemical composition and a crystalline structure formed by a geological process. This definition aligns perfectly with the criteria given in the problem.
