Answer
Salt is a mineral.
Solution
The correct answer is **salt**.
Salt (specifically, halite) is a naturally occurring inorganic solid with a regular chemical composition (sodium chloride, NaCl).
Glass and brick are man-made materials, and coal is an organic material, which does not fit the definition of a mineral.

Salt, also known as halite, is a prime example of a mineral. It crystallizes in a regular pattern and is composed of sodium and chloride ions (NaCl). Unlike coal, which is an organic sedimentary rock, salt forms naturally through evaporation of water in salty environments, making it a staple in both geology and cuisine. On the other hand, glass and brick are man-made materials. While they may resemble minerals in appearance, they lack the characteristics of being naturally occurring and inorganic. In fact, the transparency of glass can confuse people, but it’s just a clever human invention using silica and other components!
