A)34.2 mH
B)35.8 mH
C)11.4 mH
D)17.9 mH
E)22.8 mH

The impedance of the circuit can be calculated using the formula Z = V/I, where V is the rms voltage and I is the rms current. The impedance Z is also given by the formula Z = sqrt(R^2 + (X_L - X_C)^2), where X_L = 2πfL and X_C = 1/(2πfC). Solving for L using the given values, we find L = 35.8 mH.
