The voltage across L1 to L2 would be 240 V; which option lists the correct voltage across L1-L2?

Explanation:
In a typical split-phase system, each hot line (L1 and L2) is 120 V relative to neutral, and the two hots are opposite in phase. Because they’re 180 degrees apart, the voltage between them equals 120 V + 120 V, giving 240 V. So the voltage across L1 to L2 is 240 V. The 120 V option would be the line-to-neutral value, not line-to-line, and 480 V or 600 V are higher line-to-line voltages used in different systems, not the one described here.
