Assertion (A): Silver is not used to make wires.
Reason (R): Silver is a bad conductor.
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → If 'A' is true and 'R' is false
Assertion (A) — True. Electric wires are made of copper and aluminium, not silver. Silver is far too costly to be drawn into the huge lengths of wire that houses and power lines need.
Reason (R) — False. Silver is the best conductor of electricity among all metals, a little better than copper. Its cost, not its conductivity, keeps it out of ordinary wiring.
