    Answer : Option C

    Explanation :

    For t = 0 +

    iL(0-) = = 6 A

    VC(0-) = 0 V

    For t = 0+

    iL(0+) = 6

    VC(0+) = 0

    Apply KCL at node V

    6 - V = (6 + v)2

    6 - V = 12 + 2V

    - 6 = 3V

    V = VL = - 2V

    At t = 0+, = -2

    ∴

    ∴

    ∴ iL = 6 Amp

    VC = 0 V
