return value of wait() on sucess it will return the process ID of terminated child , on error it will return -1,

note - here wait(&y) i.e. wait(&status) is equivalent to waitid(-1,&status,0)

the main purpose of wait is to wait for completion of child process.

int y;

int x= wait(&y);

(C) is right the y will have exit code that is -1 (return code of child processor - y is child here)
