Explanation

DSL (Digital Subscriber Line) delivers internet service over the same copper telephone lines used by POTS (Plain Old Telephone Service). Because DSL shares the physical telephone line infrastructure, a failure in the telephone line will simultaneously take down both voice (POTS) and internet (DSL) service. This dual outage is the definitive clue. Fiber (A) uses fiber optic cables entirely separate from the phone network. Cable (B) uses coaxial cable from the cable TV infrastructure. Satellite (D) uses dish antennas and is completely independent of telephone lines. Only DSL is directly tied to the POTS copper loop, explaining why both services failed together.
