Assertion (A) : Silver is not used to make electric wires.
Reason (R) : Silver is a bad conductor.
Answer: C
Correct answer: A is true but R is false.
Silver is not used for ordinary wiring, so A is true. But the reason is its cost, not its conductivity: silver is in fact the best conductor of electricity of all metals, which is why copper, the next best and far cheaper, is used instead. R is false.
