Solution
Step-by-step verified solution
Official answer: B) Data Link Layer and Bit synchronization
Principles of LayeringBit synchronization is the primary responsibility of the Physical Layer, which deals with the transmission of raw bits over a physical medium and ensures synchronization at the bit level.
The Data Link Layer is responsible for framing, node-to-node error control, flow control, and physical addressing.
Therefore, pair (B) is incorrect.
Try the question first, then check your work.
