Solution
Copper is widely used in electric wires because it has very low electrical resistance (high conductivity), which allows electric current to flow easily with minimal energy loss.
Thus, the Assertion is true and the Reason is also true, and the Reason correctly explains the Assertion.
Correct Answer: (A) Both A and R are true and R is the correct explanation of A.

(2) Both A and R are true and R is the correct explanation of A.
(3) A is false but R is true.
(4) Both A and R are true but R is not the correct explanation of A.
