C. Aggregation switch.

Explanation:

Aggregation switch is a type of switch used to combine multiple network connections into a single link.

In Computer Networking, Aggregation switches are primarily designed to be used for connecting the Top-of-Rack (ToR) switches to a core switch or router, as the case may be.

Generally, the core switch is typically placed at the top of the data center network architecture topology.

An aggregation switch is usually designed to be large in size and has a lot of interfaces or ports for the connection of multiple networks into a single logical link.

Additionally, the connections are mainly done in parallel in order to prevent total downtime or redundancy in a network, as well as to enhance the throughput than what is obtainable in a single network.
