Why each option
Private IPv4 addresses are reserved for internal network use and are not routable on the public internet.
Private subnets are not advertised to the internet; they require Network Address Translation (NAT) to communicate with external networks.
Private address ranges are limited to specific blocks defined by RFC 1918, such as 10.0.0.0/8, 172.16.0.0/12, and 192.168.0.0/16, not unlimited.
While private networks often host multiple endpoints, this is a consequence of network design, not a defining characteristic unique to private IPv4 addressing itself.
Private IPv4 addresses are specifically designated for hosts that communicate only within a private network, preventing direct routing of these addresses on the public internet.
