Why each option
The OSI Presentation Layer (Layer 6) handles data format translation between systems and manages encryption and decryption of data.
The Presentation Layer is responsible for translating data between different formats (such as ASCII to EBCDIC, or character encoding conversions) so that applications on different systems can communicate. It also handles encryption and decryption, ensuring data is secured before transmission and decoded upon receipt.
Transmission over a physical medium (electrical signals, light pulses) is the function of the Physical Layer (OSI Layer 1), not the Presentation Layer.
Internetworking capabilities such as logical addressing and routing are provided by the Network Layer (OSI Layer 3).
Access to network services and available resources is a function of the Application Layer (OSI Layer 7).
