Concept:Metals with high electrical conductivity and good ductility are preferred for electrical wiring and conductors.
Explanation:Copper is used extensively in the electrical industry because it has very high electrical conductivity and is highly ductile.
It is commonly found in cables, wires, motors, and electrical circuits.
Aluminium is also used for overhead power lines, but copper is the primary metal for general electrical work.
Magnesium is not suitable for electrical wiring, and carbon is not a metal.
Therefore, among the given metals, copper is the correct choice.
Answer:B. Copper
