The correct answer is D. Tungsten.
Copper and aluminium are both good conductors of electricity, and they are also relatively lightweight, making them ideal for transmission and distribution of electrical power. Steel is not as good a conductor of electricity as copper or aluminium, but it is stronger and more durable, making it a good choice for use in power lines. Tungsten is a very good conductor of electricity, but it is also very heavy, making it impractical for use in transmission and distribution of electrical power.
Copper is a reddish-brown metal that is found in nature. It is one of the most common metals in the Earth’s crust, and it is also one of the most important metals for human use. Copper is a good conductor of electricity and heat, and it is also resistant to corrosion. Copper is used in a wide variety of products, including electrical wiring, plumbing, and roofing.
Aluminium is a silvery-white metal that is found in nature. It is the third most abundant element in the Earth’s crust, and it is also one of the most important metals for human use. Aluminium is a good conductor of electricity and heat, and it is also lightweight and strong. Aluminium is used in a wide variety of products, including beverage cans, building materials, and aircraft.
Steel is a strong, durable alloy of iron and carbon. It is one of the most common metals in the world, and it is used in a wide variety of products, including buildings, bridges, cars, and appliances. Steel is made by melting iron ore and adding carbon. The amount of carbon in the steel determines its properties. Low-carbon steel is soft and easy to work with, while high-carbon steel is hard and strong.
Tungsten is a hard, silvery-white metal that is found in nature. It is the heaviest metal element, and it is also one of the most expensive. Tungsten is used in a variety of products, including light bulbs, X-ray tubes, and spark plugs. Tungsten is also used in the manufacture of high-speed tools and dies.
