Encryption can take place at several layers of the OSI model, but the most common layers are the Presentation layer (d) and the Application layer (e).

The Presentation layer is responsible for encryption and decryption of data for secure transmission. It transforms data into a form that the application layer can accept. This layer formats and encrypts data to be sent across a network. It's sometimes called the syntax layer.

The Application layer, on the other hand, is the OSI layer closest to the end user, which means that both the OSI application layer and the user interact directly with the software application. This layer interacts with software applications that implement a communicating component. Such application programs fall outside the scope of the OSI model. Application-layer functions typically include identifying communication partners, determining resource availability, and synchronizing communication.

So, the answer to your question is both d. Presentation and e. Application.
