The correct answer is A) wye. The rotor windings of the motor are configured in a wye (Y) connection, which is a common configuration for induction motors. In a wye configuration, the three-phase windings are connected such that one end of each winding is joined at a common neutral point, forming a Y-shaped connection. This configuration allows for efficient power distribution and balanced load across the three phases. The other options are incorrect because: B) delta configuration has the windings connected in a closed loop, C) series-parallel connection is not a typical winding configuration for induction motors, and D) open delta is a variation of the delta configuration, which is not applicable in this case.
