Which layer uses IP addresses to send packets as defined by the OSI Model?

The Network Layer of the OSI Model is responsible for routing packets across different networks using logical addressing, which is typically implemented through IP addresses. This layer determines how data is sent between devices and manages the forwarding of packets based on their destination IP addresses.

In this layer, protocols such as the Internet Protocol (IP) operate to ensure that data can be sent from the source to the destination efficiently, handling routing and addressing tasks necessary for packet delivery. It facilitates communication between different networks and ensures that data can travel through various intermediaries to reach its intended target.

The other layers do not perform the same IP addressing function; the Physical Layer deals with the physical transmission of data, the Transport Layer manages end-to-end communication and reliability of data transfers, and the Session Layer is involved in establishing and managing sessions between applications. Each layer serves distinct purposes, but it is the Network Layer that specifically utilizes IP addresses for packet routing, making it the correct answer.
