Answer - A - SE interface uses one half of the wires for the cable that transfers data and control mechanisms and the other half for a ground point.

Key Takeaway: The SE, or single-ended connectors, use only half of the wires in the cable for data transferring and control mechanisms. The remaining wires are all used to establish a ground point. Single-ended signaling includes using a positive voltage as one and a zero voltage as zero.
