Vedclass · Answer

(A) Noble metals are metals that are resistant to corrosion and oxidation in moist air. They are found in their native state in the Earth's crust because they are chemically inert or very less reactive. Examples of noble metals include Gold $(Au)$,Silver $(Ag)$,and Platinum $(Pt)$. Iron $(Fe)$,Calcium $(Ca)$,and Magnesium $(Mg)$ are reactive metals that readily react with oxygen and moisture to form oxides or other compounds. Therefore,Platinum is the correct answer.
