Final answer:
The exec() system call replaces the current process image with a new one, maintaining the same process ID, hence false, it does not create a new process.
Step-by-step explanation:
The exec() system call does not create a new process. Instead, it replaces the current process image with a new process image. This means that the process ID remains the same, and only the executable image is replaced with that of the program specified in the exec() call. For creating a new process in systems like Unix or Linux, the fork() system call is used first to create a new process, and then exec() can be used within the new process to replace its image. In essence, exec() transforms the currently running process into a different executable, thereby enabling the system to run a different program within the same process context.
