Answer:
Hi!
It is not possible to have a deadlock involving only one process.
Step-by-step explanation:
Deadlock is only possible if there are multiple processes trying to access the same shared resources. Another way to see it is if you have shared resources only can be a deadlock if multiple processes attempt to use it.
With only one process, you can use shared resources without the risk of fall into deadlock, but you don't have concurrence either.
