Show answer & explanation
Correct answer: D
Key idea: each OSI layer has a distinct primary function; match layers to their core responsibilities.
Data Link Layer — Framing: This layer organizes raw bits into frames for reliable node-to-node transfer and handles physical addressing and error detection at the link level.
Network Layer — Routing: This layer determines paths for data to travel across networks and forwards packets toward their destination.
Transport Layer — Connection control: This layer provides end-to-end communication services, including connection establishment, flow control, and error recovery.
Presentation Layer — Encryption: This layer handles data representation, encryption/decryption, and translation between data formats.
Therefore the correct matching is: (a) Data Link Layer → Framing; (b) Network Layer → Routing; (c) Transport Layer → Connection control; (d) Presentation Layer → Encryption.
