Identify the ONE CORRECT matching between the OSI layers and their corresponding functionalities as shown.

Let us match each layer with its primary functionality:

1. (a) Network layer: Responsible for logical addressing, path determination, and (I) Packet routing between intermediate nodes across networks.

2. (c) Data link layer: Responsible for (II) Framing and error handling (error detection and correction) over a physical link between directly connected nodes.

3. (b) Transport layer: Responsible for end-to-end communication, which in the given matching corresponds to (III) Host to host communication (or process-to-process communication across hosts).

Matching the pairs:

• (a) $\to$ (I)

• (b) $\to$ (III)

• (c) $\to$ (II)

Therefore, the correct option is (B).
