Why each option

RJ-11 is the standard modular connector used for telephone lines and is the connector associated with dial-up modem connections.

ARJ-11Correct

A modem (modulator-demodulator) converts digital data to analog signals for transmission over the Public Switched Telephone Network. The physical interface between the modem and the phone line is the RJ-11 connector, a 6-position/2-contact or 6-position/4-contact modular plug standard to all telephone wall jacks in North America.

B802.11g

802.11g is a Wi-Fi wireless networking standard and has no physical connector associated with modem connections.

CRJ-45

RJ-45 is the 8-pin modular connector used for Ethernet network cables (Cat5/Cat6), not modem telephone connections.

DIEEE 1394

IEEE 1394 (FireWire) is a high-speed serial bus interface used for connecting peripherals like cameras and external drives, not modems.
