5.In three-phase transformers, the high voltage star connection is preferred. This is so because in this case A) The voltage on the star windings is lower than if they were in delta and this reduces manufacturing costs. B) The voltage on the star windings is higher than if they were in delta and this reduces manufacturing costs. C) The voltage on the star windings would be the line-to-line voltage of the system since it is a three-phase manufacturing transformer. D) THERE IS NO SOLUTION
