Correct option is C
The correct answer is (c) Copper and aluminium.
· Copper and aluminium are the two most common materials used for making wires for electricity transmission.
· They are preferred because of their excellent electrical conductivity and relatively low cost.
· Copper is known for its high conductivity, while aluminium is lighter and more cost-effective for long-distance power transmission.
Information Booster:
· Nichrome and constantan: Used in heating elements and resistors, not for general electricity transmission.
· Manganin and constantan: Used in precision resistors and temperature measurement devices, not for standard electrical wiring.
· Tungsten and manganin: Tungsten is used in light bulb filaments, and manganin in resistors, not for electrical wiring.
