Final answer:
A. Thin client. A Thin client is the best-suited PC configuration for the described workstation, as it is designed to connect to and rely on a remote server for most processing tasks.
Step-by-step explanation:
The best type of PC configuration for a workstation that will only be used to connect remotely to a server is a Thin client. Thin clients are lightweight computers that rely on a server to do most of the processing. They typically have minimal storage and processing power as they serve merely as gateways to access the server.
This makes them cost-effective and energy-efficient, especially for tasks that do not require strong local processing capabilities but depend on server-based computing resources. On the other hand, a Home server PC is meant for local network storage and management, a CAD workstation is optimized for computer-aided design with powerful graphics and processing capabilities, and an AV workstation is tailored for audio and video production with specialized hardware and software.
