How do I convert the following per unit voltages to actual voltage?

The bus admittance matrix for the power system shown in Figure 1 is given by 3-j9 −2+j6 -1+j3 0 Ybus - -2+j6 3.666-j11 -0.666+j2 −1+j3 -1+j3 -0.666+j2 3.666-j11 per unit −2+j6 0 -1+j3 −2+j6 3-j9 With the complex powers on load buses 2, 3, and 4 as shown in Figure 1. 2.1 Determine the value for V₂ that is produced by the first and second iterations of the Gauss Seidel procedure. Choose the initial guess V₂(0) = V3(0) = V4(0) = 1.0L0° per unit. (12) 2 V₁ = 1.04/0° P₁ + jQ₁ −1+j0.5 Figure 1 V₂ 0.5-10.2 0.3j0.1

If the load draws a current of 2727 A, in phase, from a generator, which of the following statement is true? O A. The reactive power is flowing from generator to the load and the real power is flowing from the load to the generator. O B. Since the current is in phase with the generator voltage, both the real and reactive power is flowing from the generator to the load. O .Since the current is leading the generator, both the real and reactive power is flowing from the load to the generator. O D. The real power is flowing from generator to the load and the reactive power is flowing from the load to the generator. O E. None of the other choices are correct
