Correct Answer is :
B. Process-to-process delivery
Explanation
Node-to-node delivery means transferring data between two directly connected devices (nodes) on the same network segment. This is the main job of the Data Link Layer.
The Transport Layer (Layer 4 in the OSI model) ensures that data is delivered from one process (application) on a device to another process on another device.
