Conductance ($G$) is the real component of admittance.

Susceptance ($B$) varies with frequency as $B_L = \frac{1}{2\pi fL}$ and $B_C = 2\pi fC$.

Resistance ($R$) is considered constant in ideal circuit theory across frequency ranges.

$G$ is measured in Siemens ($S$) or Mho ($Omega^{-1}$).

Simplifies calculation of active power dissipation ($P = V^2 G$).

Provides a real-valued parameter for power analysis.

Does not account for frequency-dependent skin effect which may increase AC resistance at very high frequencies.

Power system load modeling.

Calculation of active power losses in parallel networks.

At very high radio frequencies (RF), the 'skin effect' causes effective resistance to increase, which would technically decrease $G$. However, in standard 'Basic Electrical' context, components are treated as ideal and frequency-independent.

Option A and B are incorrect because they imply dependency on frequency, which only applies to reactance components ($X_L$ or $X_C$).
