Show answer & explanation
Correct answer: A
When a deadlock is detected, one recovery strategy involves rolling back or aborting one of the involved processes to release resources.
The primary difficulty arising from this approach is starvation. If the system repeatedly selects the same process for rollback due to cost factors or priority, that process may never complete its execution.
To mitigate this, operating systems implement mechanisms like aging or cost analysis to ensure fair resource allocation during deadlock resolution.
