Answer:
A) Diamond and garnet
Step-by-step explanation:
An abrasive is a material used for grinding, polishing, or shaping a surface by wearing away the material. The choice of abrasive material depends on the material being worked on and the desired finish.
Diamond and garnet are two examples of abrasive materials. Diamond is the hardest material known and is used for grinding and polishing hard materials such as metals, ceramics, and glass. It is also used in diamond-tipped cutting tools. Garnet is a mineral that is used as an abrasive in sandpaper, grinding wheels, and other abrasive applications. It is particularly effective for grinding and polishing wood, metal, and plastic surfaces.
Calcite and gypsum are minerals, but they are not commonly used as abrasives. Apatite and galena are minerals that are too soft to be used as abrasives. Talc and graphite are also soft minerals and are used for their lubricating properties, rather than as abrasives.
