Which of the following TCP/IP layers selects the best path through the network for packets to travel?

TCP/IP model is a framework for the Internet Protocol suite of computer network protocols
that defines the communication in an IP-based network. It provides end-to-end connectivity
specifying how data should be formatted, addressed, transmitted, routed and received at the
destination. This functionality has been organized into four abstraction layers which are used
to sort all related protocols according to the scope of networking involved.
