Answer

Implementing the Internet Protocol (IP) to distinguish and forward data between networks Explanation 1. Identify router's role in networking A router's main purpose is to use the Internet Protocol (IP) to route data packets between different networks based on destination IP addresses. 2. Eliminate unrelated options Routers do not primarily handle high-speed links between IXPs (specialized exchange facilities), modulate/demodulate signals (modems' role), or establish physical WAN connections (function of other devices/interfaces).
