D Correct answer
Explanation

RJ-11 is the standard 6-pin modular connector used for telephone lines and connecting modems to phone jacks. It typically uses 4 or 6 wires. RJ-45 (option A) is the larger 8-pin connector used for Ethernet networks. RJ-10 doesn't exist as a standard connector type, and COM1 is a serial port designation, not a physical connector type.
