What is an amateur radio station that connects other amateur stations to the internet?

A "gateway" is the correct term for a station that acts as a bridge connecting an amateur radio network to the internet. Systems like EchoLink, IRLP, and D-STAR use gateways to route local RF traffic across global IP networks. The distractors represent other specific types of stations. A standard "repeater" receives and retransmits RF signals to extend local range, but doesn't inherently connect to the internet. A "digipeater" does the same thing specifically for digital packet data. A "beacon" simply transmits a one-way continuous signal to help other stations determine propagation conditions.
