Best answer
Right choice is (a) True

For explanation: After the shell has issued the prompt and the scanning for meta-characters has been performed it passes the command on the command line to the kernel for execution. After that, the shell waits for the command to complete its execution and normally we can’t do any other work while the command is executing.
