Which is an example of Steno's Law?

What is an example of Steno's Law based on the given options?

The example of Steno's Law is option b which states - the crystal faces of quartz, regardless of the size of the crystal, are always 120 degrees apart.

Explanation:

The correct option centering around the example of Steno's Law or the law of constancy of interfacial angles is option b. The crystal faces of quartz, regardless of the size of the crystal, are always 120 degrees apart. This law, named after Nicolas Steno, states that the angle between corresponding faces on a crystal is the same for all specimens of the same mineral, regardless of the size or where the specimens are found. Option a, Option c, Option d, and Option e are incorrect. A microscopic crystal of garnet and a gemstone-grade crystal of garnet will have the same crystalline shape according to Steno's Law. All minerals, regardless of their size, can be crystalline. Polymorphs like graphite and diamond do not have the same crystal shape.
