Detailed Solution

Concept- It is a metal that is found in group 8 of the periodic table and the first transition series. With additions like nickel, vanadium, manganese, and others, it is used to create alloy steels like carbon steels. Calcium is an alkaline earth metal that reacts with air to create a black oxide-nitride coating.
Tell us about the metal that is most common on earth. Aluminum is the most common metal on the world and makes up around 8% of the Earth's crust. But it is never discovered alone or in a pure condition; it is always present in mixtures with numerous other elements. Alum and aluminium oxide are two of the most frequently found aluminium compounds. Let's think about the query now. Iron is the second most common metal on earth, while calcium comes in third. 3.6% of calcium, 5.0% of iron, and Na, K, Mg, and Ti are close behind.Due to the ease with which they may be created during supernova nucleosynthesis, the elements from carbon through iron are significantly more common in the universe. Rarely is calcium discovered in its elemental state.
Iron and calcium are the second and third most common metals in the crust of the planet.
Hence, the correct option is 3.
