Step-by-step explanation:
The correct answer to the question: "This puts the current router into static _______ mode" is c) Unicast. When a router is put into static unicast mode, this means that it is configured to send or receive data to a single, specific recipient instead of broadcasting to multiple devices or handling multiple streams like in multicast. Static unicast routes are commonly used in networking when a dedicated path is needed to ensure that data packets reach a specific destination without unnecessary distribution along the way.
