Which of the following represents a key characteristic of 'Full-Duplex' network communication?

A. Data can be transmitted and received simultaneously over the same link channel.

B. Data requires analog modulation steps at every connection node.

C. Data must pause at every node before moving forward.

D. Data can be transmitted in only one direction permanently.

Answer: Option A
