Final answer:
The best option for WAN connectivity in remote locations is Satellite Internet, which doesn't rely on ground infrastructure and can reach rural areas where other wired services cannot.
Step-by-step explanation:
The option that is perfect for remote locations with limited Wide Area Network (WAN) connectivity possibilities is b) Satellite. Satellite Internet is a method of connecting to the Internet using satellites orbiting the Earth. Unlike DSL, fiber optics, or leased lines, satellite communication does not require extensive ground infrastructure and can provide connectivity to areas where traditional wired services are not economically viable or physically possible. The signal is transmitted from a ground station to a satellite and then down to the user's satellite dish, making it an excellent choice for remote or rural locations.
