    Given below are two statements:
    Statement-I: The reactance of an ac circuit is zero. It is possible that the circuit contains a capacitor and an inductor.
    Statement-II: In ac circuit, the average poser delivered by the source never becomes zero.
    In the light of the above statements, choose the correct answer from the options given below:
    1. (1)Both Statement I and Statement II are true.
    2. (2)Both Statement I and Statement II are false.
    3. (3)Statement I is true but Statement II in false.
    4. (4)Statement I is false but Statement II is true.
