Which description matches a high bandwidth connection that runs over a telephone line?

Explanation:
The concept here is using a telephone line to deliver high-speed data. Dial-up uses the same phone line but transfers data at very slow speeds, so it’s not high bandwidth. Satellite and cable are different media entirely—satellite is wireless via space, and cable runs over coaxial cable, not a telephone pair. Digital Subscriber Line, or DSL, uses the existing copper telephone line but transmits data on higher frequencies, allowing much faster speeds while you can still use voice service (often with filters). Because it provides a much higher bandwidth over a telephone line, DSL is the description that fits best.
