Explanation

IPv4 address classes are determined by the first octet: Class A spans 1–126 (e.g., 10.x.x.x), Class B spans 128–191 (e.g., 172.x.x.x), and Class C spans 192–223 (e.g., 192.168.x.x). The address 192.168.1.15 starts with 192, placing it firmly in the Class C range. Option A (10.x.x.x) is Class A private, Option C (172.20.x.x) is Class B private, and Option B (169.254.x.x) is an APIPA (Automatic Private IP Addressing) link-local address, not a standard class.
