Answer:

D. Malleability

Explanation:

Gold is made up of the element Au and it is a metal.

Pyrite is iron sulfide and it is a non-metal.

They have very similar appearance to such an extent that pyrite is widely called the fool's gold.
To distinguish between the two, we simply explore their metallic properties.
Gold is malleable. Pyrite is not. It will crumble under pressure.
