Question

which properties make a metal a good material to use for electrical wires? malleability and reactivity conductivity and ductility ductility and malleability reactivity and conductivity

Explanation:

Conductivity allows metals to carry electric current. Ductility means metals can be drawn into wires. These are key for electrical wires. Reactivity is not beneficial as it may cause corrosion or chemical changes, and malleability (ability to be hammered into sheets) is not relevant for wire - making compared to ductility.

Answer:

B. conductivity and ductility
