Which statement correctly pairs the type of signaling with its typical connection configuration?

Explanation:
Current loop signaling relies on the same current flowing through every device in the loop. To keep the signal intact, devices are wired in series so the loop current is the same from start to end. The transmitter sets this loop current (such as 4–20 mA), and each device taps the current to produce its output or measurement without changing the current through the others. If devices were connected in parallel, the current would split unpredictably, distorting the signal and defeating the purpose of a current loop. In contrast, voltage-type signaling typically places devices across the same supply (in parallel), so they all see the same voltage. So the correct pairing is that current loop devices are connected in series.
