Answer:
The correct option is;
a. LAN
Step-by-step explanation:
The computer networks listed vary in their transmission medium from the wired transmission medium using the network cable for the Local Area Network (LAN) network, to the wireless transmission network used in the Wide Area Network (WAN), while the Wide Area Networks, (WAN) consists of several LAN networks connected to a larger network through telephone lines.
Of the three network types, the type that has the least amount of data loss is the LAN, due to its structure, being the smallest unit of wired network that can handle direct port to port data flow through physical network switches, which ensures sufficient bandwidth and lesser opportunity for congestion which results in packets of data losses.
