The answer is: D. new process created by parent process
Correct ANS=D
The Linux tool described in the question is most likely the fork() system call, which creates a new process by duplicating the calling process. When fork() is called, it returns a process ID (PID) to the parent process and a value of 0 to the child process. If an error occurs during the fork() call, a negative value is returned. Therefore, the operation described in the question results in a new process being created by the parent process, and the process ID being sent to the parent process. This is what the fork() system call does in Linux.
