Answer - C - The ratio between the maximum peak voltage and minimum voltage on a line is called VSWR.

Key Takeaway: Voltage standing wave ratio, or VSWR, is the difference between maximum peak voltage and minimum voltage on a line. It is represented as a ratio, for example 1.3:1. It is a measure of how efficiently radio-frequency power is transmitted from a power source through a transmission line into a load.
