Participation reward: 3 Wealth. Reward for correct answer: 10 wealth. The line voltage of a three-phase symmetrical power supply is 380 V; it is connected to a Y-connected symmetrical load without a neutral wire. If one phase is suddenly disconnected, the phase voltage of the remaining two phases will be ( ). A. 380V B. 220V C. 190V D. Unable to determine. New activities have started in the production area; the prizes are attractive, so hurry and participate: 【Producing Summer】The production area has entered the \"train during the hot summer days\" mode
