A Public IP Address is the correct answer because it serves as a unique identifier for devices directly connected to the internet. Public IP addresses are assigned by Internet Service Providers (ISPs) and are globally unique, allowing devices to communicate with one another across the internet. This type of address is essential for routing internet traffic to the correct location, ensuring that data sent over the internet reaches its intended destination.

In contrast, Private IP Addresses are used within local networks and are not routable on the internet. They are meant for internal use within a home or organization, making them unsuitable for direct internet communication. Static IP Addresses refer to a fixed address that doesn't change over time; while they can be public, they are not inherently unique because static can apply to both public and private addresses. Dynamic IP Addresses are assigned temporarily and can change over time when devices connect to the network; while they can also be public, they do not provide a stable identifier over long periods.
