The correct answer is: C. Copper and Tin
Bronze is an alloy of copper and tin. It is one of the oldest metal alloys, and was first used in the Bronze Age. Bronze is harder and more durable than copper, and it can be cast into complex shapes. It is also resistant to corrosion, making it ideal for use in marine applications.
Tin is a soft, silvery-white metal that is found in nature as the mineral cassiterite. It is a relatively rare element, making up only about 0.001% of the Earth’s crust. Tin is used in a variety of alloys, including bronze, pewter, and solder. It is also used in the production of tinplate, which is a type of steel that is coated with tin to prevent corrosion.
Copper is a reddish-brown metal that is found in nature as the mineral chalcopyrite. It is the second most abundant metal in the Earth’s crust, making up about 0.06% of the total mass. Copper is a good conductor of electricity and heat, and it is also used in a variety of alloys, including bronze, brass, and cupronickel.
Iron is a hard, gray metal that is found in nature as the mineral hematite. It is the most abundant metal in the Earth’s crust, making up about 4.6% of the total mass. Iron is a good conductor of electricity and heat, and it is also used in a variety of alloys, including steel.
Zinc is a bluish-white metal that is found in nature as the mineral sphalerite. It is the 24th most abundant element in the Earth’s crust, making up about 0.007% of the total mass. Zinc is used in a variety of alloys, including brass, bronze, and galvanized steel. It is also used in the production of batteries, pigments, and rubber.
