Answer
Correct option: A.
Adamantine
Lustre or luster is the way light interacts with the surface of a crystal, rock, or mineral. Adamantine minerals possess a superlative lustre, which is most notably seen in diamond. Such minerals are transparent or translucent, and have a high refractive index $($of $1.9$ or more$).$ Minerals with a true adamantine lustre are uncommon.
