Answer:
D. Configure a WiFi infrastructure network
Step-by-step explanation:
In a WiFi infrastructure network, there is an access point that enables wireless communication between devices in the network. The setup will allow for file sharing between the computers and enable printing to a centrally located printer, whereas with a WiFi ad hoc network, there is no access point as the network is decentralized. The computers have a peer to peer connection, which allows direct file-sharing but, printer sharing is difficult as the computer users need to be in the same work-group.
