Final answer:
Satellite Internet is the correct answer because it is a long-distance line-of-sight Internet service, allowing remote and rural areas to access the Internet where traditional ground-based infrastructures like DSL, cable, and fiber optics are not applicable.
Step-by-step explanation:
Among the internet services mentioned, satellite Internet is a long-distance line-of-sight Internet service. Satellite Internet relies on communication satellites in geostationary orbits to provide internet access to users. Unlike DSL and cable Internet, which use terrestrial cables, and fiber optics, which use light through glass or plastic cables, satellite Internet can provide connectivity in remote and rural areas where ground-based infrastructure is not feasible.
While fiber optic technology does enable long-distance communications and offers numerous advantages such as low loss, high bandwidth, and reduced crosstalk, it is not a line-of-sight system and thus is not the answer to the question. Fiber optics make use of total internal reflection within thin fibers of plastic or glass to transmit light, which carries data, allowing for the transmission of telephone, internet, and cable TV signals over long distances without a direct line of sight.
