Select the symbol of Zinc.

The Periodic Table's symbol for zinc, which has the atomic number 30 and is a transition earth metal, is "Zn." Another useful metal that we utilise on a daily basis is zinc. It is a component of those components that people have been enhancing for a very long time. Metal that has a bluish-white hue and a shiny look is zinc. Although it is naturally brittle, at higher temperatures it shows good malleability and ductility. Zinc was given its name by the German alchemist Paracelsus. It possibly derives from the German word "zinn," which means "tin," or "zinke," which means "spiky" (for the spiked forms of the zinc crystals).

As a general guideline, when assigning symbols to elements, the first letter of the newly named element should be used, and if that letter already exists for a previously identified element, the second or third letter should be used in lower case after the first letter used in upper case. Thus, in the current periodic table, zinc is denoted by the letter "Zn."

Hence, option D is correct.
