Answer: C - A Mesh topology provides the most redundancy of any topology.

Key Takeaway - Since a Mesh topology is defined by each node being connected to every other node, it provides the most connection redundancy of any topology, and is therefore the most fault-tolerant. Bus and Ring topologies will fail to function if once computer fails. Star topologies are much more fault-tolerant and cost-effective than Mesh topologies, but where price is not an issue and up-time is of the most importance, a Mesh topology is the preferred path.
