Correct answer: D
In IPv4 classful addressing, Class C addresses reserve the first 3 bits as '110' within the first octet. The network portion consists of the first 24 bits total. This leaves 21 variable bits (24 - 3) to identify specific networks, resulting in a total of 2^21 possible Class C networks.
