The Correct Option is B

Solution and Explanation


In domestic electric mains supply, both the voltage and current are alternating, meaning they vary sinusoidally with time. Therefore, the correct answer is AC voltage and AC current. This is typical for household electrical systems where both the voltage and current are alternating, as opposed to DC (direct current) systems which have a constant value. Thus, the correct answer is option (2): AC voltage and AC current.
