The elements that have completely filled outermost shell are Noble gases.

Here's why:

A. Halogens: Halogens are the elements in Group 17 (formerly Group VIIA) of the periodic table. They have seven electrons in their outermost shell, so they are not completely filled.

B. Metals: Metals do not have a completely filled outermost shell. They tend to lose electrons to achieve a stable electron configuration.

C. Noble gases: Noble gases are the elements in Group 18 (formerly Group VIII) of the periodic table. They have a completely filled outermost shell, which makes them very stable and inert.

D. Nonmetals: Nonmetals do not have a completely filled outermost shell. They tend to gain or share electrons to achieve a stable electron configuration.

So, the correct answer is C. Noble gases.
