L1-L3 stands for lines 1-3 in three-phase systems. Which option correctly identifies this?

Explanation:
In a three-phase system, L1, L2, and L3 designate the three live conductors that carry the phase voltages. These are the lines—the line conductors that connect the source to the load. They are separate from neutral and ground. Therefore, L1-L3 correctly identifies the lines 1-3. The other terms don’t fit electrical terminology here: ground lines would refer to protective earth, while lanes and levels aren’t used for this context.
