Answer:
a. new, running, waiting, ready, and terminated.
Explanation:
The process in a computer system can have different states and these are:
-New: When the process is created.
-Ready: When the process is waiting to be executed.
-Running: When the process is chosen to be executed.
-Waiting: When the process is expecting for something to happen.
-Terminated: When the process is not running anymore.
According to this, the answer is that the possible states of a process are: new, running, waiting, ready, and terminated.
