Solution
The correct option is C Noble gas
Noble gases are found in the air only in traces. Noble gases are also called as inert gases, which do not react chemically with other elements. The noble gases are helium, neon, argon, krypton, xenon and radon. Metals are the elements which possess the property like shiny, solid, ductile, malleable, good conductor of electricity, sonorous and which have high melting and boiling point. Non-metals are the elements which do not possess the properties of metals as they are soft, brittle, does not conduct electricity and have low melting points and boiling points. Metalloids are the elements which are neither completely like metals nor fully like non-metals. They show the properties of metals and some properties of non-metals. Example: Boron, Arsenic.
