Right answer is (d) 120⁰ The best I can explain: In delta-connected system, the currents IR, IY, IB are equal in magnitude and they are displaced by 120⁰ from one another. From the manner of interconnection of the three phases in the circuit, it may appear that the three phase are short circuited among themselves.
