The correct answer contains the complete list of layers of the OSI (Open Systems Interconnection) Model, which is a framework used to understand and implement interactions in network communication. The OSI Model consists of seven distinct layers, which are as follows:

  1. Application Layer: This is the topmost layer, where end-user applications interact with the network.
  2. Presentation Layer: This layer is responsible for translating data into a format that the application layer can understand. It deals with data encoding, encryption, and compression.
  3. Session Layer: This layer manages and controls the connections between computers. It establishes, maintains, and terminates sessions between applications.
  4. Transport Layer: This layer ensures that data is transferred correctly and reliably between devices, managing error detection and recovery as well as flow control.
  5. Network Layer: This layer handles the routing of data, determining the best path for data to travel across the network.
  6. Data Link Layer: This layer is responsible for node-to-node data transfer and handles error detection and correction from the physical layer.
  7. Physical Layer: The lowest layer, which deals with the physical aspects of network communication, including cables, switches,
