A small-office customer needs three PCs to be configured in a network with no server. Which of the following network types is the customer's BEST choice for this environment?

A workgroup network is a peer-to-peer networking model ideal for small environments with fewer than 10 computers and no central server, where each computer manages its own security and shares resources directly.

A public network refers to an untrusted network environment like a coffee shop Wi-Fi, not a type of internal network configuration for an office.

A wide area network (WAN) connects networks over large geographical distances and is not applicable for a small office's internal network setup.

A domain network requires a dedicated server (Domain Controller) to manage users, computers, and resources centrally, which is explicitly stated as not present in the scenario.
