Which term describes a data link that allows data to be transmitted in both directions at the same time?

Explanation:
Two-way, simultaneous data transmission is described by duplex. Simplex is one-way, so data only travels in a single direction. Half-duplex allows bidirectional data but not at the same time—you take turns. Analog isn’t a data-link mode for digital two-way communication. Among the options, duplex best fits a link that supports data moving in both directions at once; if you see the exact term full duplex, that means simultaneous two-way transmission, but the given choice still captures that concept.
