What does RJ-11 signify?

USB Cable type
Ethernet connector plug type
Telephone connector plug type
Coaxial cable

The correct answer is: Telephone connector plug type

RJ-11 signifies a telephone connector plug type, as it is a specific type of registered jack used for connecting telephones. USB cable type (A) would be indicated by a USB-A, and Ethernet connector plug type (B) would be designated as an RJ-45. Coaxial cable (D) does not use an RJ type of connector at all, and instead is typically designated by its type of connector (such as BNC or F-type). Therefore, only choice C accurately describes what RJ-11 signifies.
