Mesh networks:

a. usually provide relatively long routes through the network (compared to ring networks)

b. require more processing by each computer in the network than in star or ring networks

c. do not use decentralized routing

d. do not have much capacity wasted by network status information

e. do not have many possible routes through the network to prevent one circuit from becoming overloaded

B) Require more processing by each computer in the network than in star and ring networks

Explanation:

Meshnet which refers to mesh networks is one of the topologies of computer networks. In this topology, the nodes are all connected directly to each other and to as many many other nodes that cooperate with each other (nodes here refers to PCs, bridges routers etc), this kind of connection prevents dependence on a single node for communication as all nodes participates in the passing of information, as a result each computer in a mesh requires more processing work than in star and ring networks.
