Assuming the following C code snippet, select all statements that are correct:

int main$($void$)\{$

pid$\_$t pid;

pid $=$ fork$()$;

if $(!$pid $)\{$

printf$("$Child process: my id is $\%$d$,",$ getpid$())$;

printf$("$my parent's id is $\%$d

$",$ getppid$())$;

$\}$

else $\{$

printf$("$Parent process: my id is $\%$d$,",$ getpid$())$;

printf$("$my child's id is $\%$d

$",$ pid$)$;

$\}$

return $0$;

$\}$

Group of answer choices

The code will always execute as intended and will print all valid process ids for both the parent and the child processes

The parent process uses function getppid$()$ to determine its own process id

The parent process does NOT need to call any special function to determine its child's id since fork returns that id to the parent

To synchronize parent and child processes in this context, the parent process needs to wait for the child to finish first, using an appropriate language primitive to do so$.$

The child process uses function getppid$()$ to determine its own process id
