The correct option is D
silvery-white

Properties of Zinc Metal
Colour: The colour of zinc metal is bluish-grey.
Explanation
Zinc is a chemical element with the symbol Zn and atomic number 30. It is a bluish-grey metal that is brittle at room temperature and has a low melting point. Zinc is commonly used in alloys to create materials with improved strength and corrosion resistance.
When freshly produced, zinc has a shiny surface with a bluish-grey colour. However, over time, the surface of the metal reacts with oxygen in the air to form a protective layer of zinc oxide. This layer gives the metal a duller appearance and may result in a white or greyish colour.
In summary, the colour of zinc metal is bluish-grey, although it may appear white or greyish due to the formation of a protective layer of zinc oxide on its surface.
