Answer: C

Explanation:

The code snippet establishes an ncclient connection to a Cisco Nexus device. The ncclient library in Python is used for NETCONF protocol operations with network devices. The connect method from the manager class is used here to create a session with the device, which is maintained for the

duration of the ‘with’ block, ensuring proper resource management and closure of the session.
