Information on the image

In an AC circuit containing an inductance and a capacitance in series, the current is found to be maximum when the value of the inductance is 0.2 henry and capacitance is 8x10-7 F. The angular frequency of the input voltage must be equal to ( Angular frequency @ = 2nf ) . A 2500 B 1581.14 C 4x 10-4 D 6.32x 10-4
