 In the Open Systems Interconnection (OSI) model, the Session layer manages the setting up and taking down of the association between two communicating end points that is called a connection. Means it provides the mechanism for opening, closing and managing a session between end-user application processes.

The presentation layer ensures that the communications passing through are in the appropriate form for the recipient. That means Presentation layer responsible for encoding and decoding of data, read- https://www.cse.iitb.ac.in/synerg/lib/exe/fetch.php?media=public%3Acourses%3Acs348-spring08%3Aslides%3Atopic03-phy-encoding.pdf

Transport layer responsible for end-to-end communication and Network layer transfer data sequences from a source to a destination . so session layer is the right choice if u go with the options.
