Answer

Brief Explanations:

In mineralogy, a key property is hardness, defined by the ability of a mineral to scratch another. A harder mineral will leave a mark on a softer one when rubbed together. Density is unrelated to scratching ability. Since Mineral A scratches Mineral B, A must be harder.

Answer:

A. Mineral A is harder than mineral B.
