Explanation:
Detailed explanation-1: -The correct answer is Dial-up. Dial-up is the slowest type of internet connection.
Detailed explanation-2: -A dial-up connection uses a standard phone line and analog modem to access the Internet at data transfer rates (DTR) of up to 56 Kbps. A dial-up connection is the least expensive way to access the Internet, but it also slowest connection.
Detailed explanation-3: -Modern dial-up modems typically have a maximum theoretical transfer speed of 56 kbit/s (using the V. 90 or V. 92 protocol), although in most cases, 40–50 kbit/s is the norm. Factors such as phone line noise as well as the quality of the modem itself play a large part in determining connection speeds.
