Explanation

A dial-up modem has two RJ-11 ports: LINE (connects to the telephone wall jack to receive a dial tone) and PHONE (connects to a handset). The LINE port must be connected for the modem to detect a dial tone. RJ-11 is the correct connector type for telephone lines-it is the small 6-position plug used in phone cabling. RJ-45 (options A and C) is a larger Ethernet connector and is not used for telephone/modem connections. Checking the phone port (D) would be incorrect because that port is for a handset, not the incoming phone line.
