Answer: D - The presentation layer of the OSI model manages encryption and decryption of data.

Key Takeaway: This layer provides independence from different data representation formats (such as encryption) by translating from application to network format and vice versa. The presentation layer works to transform data into the form that the application layer can accept. This layer formats and encrypts data to be sent across a network, providing freedom from compatibility problems.
