Which of the following is a commonly used home internet access method?

Correct answer: DSL (Digital Subscriber Line)

Among the listed choices, DSL is the best answer for a common home internet access method because it uses existing telephone lines and has historically been widely available for households.

• DSL: uses telephone lines for broadband internet access and is widely available.

• Fiber optic cable: fastest and very reliable where available, but it is not the generic “most common” choice in this option set.

• Satellite: mainly useful where wired infrastructure is unavailable, especially remote areas.

• Cellular data: common for mobile access, but the question is about a home internet access method.
