Solution

The correct option is B

Both assertion and reason are true but reason is not the correct explanation of assertion


The members of the group have eight electrons in their outermost orbit (except helium which has two electrons). Thus, they have a stable configuration. Group 18 elements are gases and chemically unreactive, which means they don’t form many compounds. Thus, the elements are known as inert gases.
