Answer:
Option (B)
Explanation:
Crystals are usually defined as those substances that are comprised of atoms, ions, and molecules, and they are oriented in a very well-developed and ordered microscopic structure. These crystals are interlinked to one another by strong chemical bonds, namely the metallic, covalent, ionic and Vander Waals bond. In nature, these crystals form when any liquid undergoes cooling and solidifies.
The study of crystals is commonly known as crystallography and is directly associated with the minerals.
Thus, the correct answer is option (B).
