What is the shell primarily made of?

Explanation:
Shells are mineralized structures, and their main material is calcium carbonate. The crystals of calcium carbonate (often in forms like calcite or aragonite) build the hard, protective layers that give shells their strength. An organic protein-rich matrix helps organize and bind these crystals, and there is some moisture, but these components are present in far smaller amounts than the mineral. That mineral dominance is why calcium carbonate is the correct choice.
