In a dc-ac 3-phase MOSFET bridge inverter circuit, the switches are marked in a sequence as 1, 2, 3 in the top-half and 4, 5, 6 in the bottom half of the bridge. The triggering sequence of switches that gives balanced output voltage is
(A) 1, 2, 3, 4, 5, 6 (B) 1, 5, 3, 4, 2, 6
(C) 1, 6, 2, 4, 3, 5 (D) 1, 4, 2, 5, 3, 6
(A) 1, 2, 3, 4, 5, 6 (B) 1, 5, 3, 4, 2, 6
(C) 1, 6, 2, 4, 3, 5 (D) 1, 4, 2, 5, 3, 6
