The correct answer is A. 1.544 Mbps.

A T1 line is a digital telecommunications line that can carry data at a rate of 1.544 Mbps. It is commonly used for point-to-point connections between two locations, such as between two offices or between a customer location and a service provider.

T1 lines use Time-Division Multiplexing (TDM) technology, which divides the available bandwidth into 24 channels, each of which can carry up to 64 Kbps of data. This results in a total bandwidth of 1.536 Mbps (24 channels x 64 Kbps), with an additional 8 Kbps used for framing and signaling, bringing the total to 1.544 Mbps.

It's worth noting that T1 lines are becoming increasingly rare as faster and more cost-effective alternatives, such as T3, Ethernet, and fiber optic connections, become more widely available. However, they may still be used in certain situations where dedicated bandwidth and reliability are essential.
