This question was addressed to me by my college director while I was bunking the class.

This interesting question is from Inter Connection of Three-Phase Sources and Loads topic in portion Polyphase Circuits of Network Theory

Answer 1

Correct option is (c) line and line

Easiest explanation: The voltage between line and line is called line voltage. And the voltage between line and neutral point is called phase voltage. The currents flowing through the phases are called the phase currents, while those flowing in the lines are called the line currents.
