A Correct answer
Explanation

Metals are lustrous because of the free electrons present in them. The free electrons can move freely in the metal causing any light incident on them to get reflected back. This reflection is specular reflection rather than diffused and thus the metal surface appears shiny or lustrous.
Hence, option $A$ is correct.
