The correct option is D
silvery-white
Explanation for correct option
(D) The color of Zinc metal is silvery.
- An electron gets excited to a higher energy orbital from a lower energy d orbital. The frequency of light absorbed is proportional to the excitation energy.
- This frequency is usually in the visible range.
- The color seen corresponds to the complementary color of the light absorbed.
- Zinc (Zn) is a silvery-white metal.
Hence, option (D) is correct. The color of Zinc metal is silvery.

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.

Zinc is a bluish-silver, lustrous metal that tarnishes in moist air, producing a layer of carbonate. It is somewhat brittle at room temperature but malleable above 100 oC. It is a fair conductor of electricity, and burns in air with a bright bluish-green flame producing white clouds of the oxidê
