Final Answer :
B
Explanation :
The VARs (Volt-Ampere Reactive) for the capacitor in an RLC parallel circuit can be calculated using the formula VARs = V^2 / Xc, where V is the voltage across the circuit and Xc is the capacitive reactance. Given V = 208 volts and Xc = 81 Ω, VARs = 208^2 / 81 = 534.12.
