Solution

The correct option is D Lustre
Metals have unique ability to reflect light from their pure surface (without impurities). This results in a shining surface. This property is known as lustre. The word traces its origins back to the latin name - ‘lux’, meaning ‘light’ and generally implies radiance, gloss, or brilliance.
