Consider the program given below, where a process creates a thread by calling a function named as "runner" that was defined before. The "runner" function changes the value of "i"; int i = 5; int main() { pthread_t pid; pthread create (pid,NULL,runner, NULL); printf("%d",i); //line #1 } Which of the following is correct? Select one: O Line #1 will be executed after the thread terminates The updated value of i will be displayed The thread can not run in parallel with the main process. The thread will be called after the main function is completed The main process may display 5.
