Which statement best describes a T3/DS3 digital carrier?

Explanation:
T3/DS3 is a high-capacity digital carrier in the North American T-carrier system. It carries about 44.736 Mbps of data, which is commonly rounded to 45 Mbps. This speed comes from multiplexing 28 DS1 channels at 64 kbps each plus overhead, creating a single, high-bandwidth channel. So the best description is a digital carrier of roughly 45 Mbps. It's not a 1 Mbps link, and while it can run over copper or fiber, the defining feature here is the data rate rather than the medium.
