A two-terminal network consists of a coil having inductance L and resistance R shunted by a capacitance C. The poles and zeros of the driving-point impedance function Z(ω) are located as poles at $$ - \frac{1}{2} \pm {\text{j}}\frac{{\sqrt 3 }}{2}$$   and zero at -1. If Z(0) = 1, the values of R, L and C are

A. 1Ω, 1H and 1µF

B. 1Ω, 1H and 1F

C. 1Ω, 1µH and 1F

D. 1kΩ, 1H and 1F

Answer: Option B
