Which term means composed of crystals or related to crystals?

• A. Crystalline
• B. Crystal
• C. Crystal structures
• D. Crust

Answer: (A)

The idea being tested is the adjective used to describe something that has a crystal-like structure or is made up of crystals. Crystalline is the form used to express that idea. It comes from crystal and is used to describe solids with an orderly, repeating arrangement of atoms in a lattice, i.e., a crystal-like nature. That makes it the precise term for “composed of crystals or related to crystals.” The other terms are different parts of speech or refer to different meanings: crystal is a noun for the solid or a single crystal; crystal structures describes the arrangement of atoms rather than a property; crust is unrelated.
