Extracted text: The zero-, positive-, and negative-sequence bus impedance matrices for a two-bus three-phase power system are [0.10 Zbus 0 = j %3D per unit 0.10] 0.20 0.10 Zbus 1 = Zbus 2 = per unit 0.10 0.30 The prefault voltage is 1.0 per unit. The per-unit voltage at bus 2 for a bolted double line-to- ground fault at bus 1 is: Select one: O a. V2ag= 0.75.130.9, V2bg=0.57.130.1. V2cg=0.57L0°. O b. V2ag= 0.75.0°, V2bg=0.57--130.9, V2cg=D0.57.130.9°. Oc. V2ag= 0.75.0°, V2bg=D0.57.130.9, V2cg=0.57.-130.9°. O d. None
