The load shown in the figure is supplied by a 400 V (line-to-line), 3-phase source (RYB sequence). The load is balanced and inductive, drawing 3464 VA. When the switch S is in position N, the three wattmeters W1, W2 and W3 read 577.35 W each. If the switch is moved to position Y, the readings of the wattmeters in watts will be:

A. W1 = 1732 and W2 = W3 = 0
B. W1 = 0, W2 = 1732 and W3 = 0
C. W1 = 866, W2 = 0 and W3 = 866
D. W1 = W2 = 0 and W3 = 1732
