B. They are less costly than public IP addresses – because private IPs are free and don’t require purchasing from an ISP. C. They can be assigned to devices without Internet connections – making them ideal for internal networks. The other options are incorrect because private IPs aren’t routed on the Internet, require NAT for external access, and can still cause conflicts if not managed properly.
B & E are the best options for the question asked. A and D are apparently wrong. B. Correct, because private IPs do not cost money, while public IPs need to be purchased from ISP. E. The same IP address can be used in multiple private networks without causing conflicts. This is actually a purpose of NAT. C. Incorrect, because you can assign public IPs to devices if they have no connections to the internet. For example, in an isolated lab environment, you can assign any IPs (except special addresses like network ID, broadcast, multicast) to devices, and they can function well within the environment.
But ip conflicts are still possible with ipv4, within the same private network.
