Consider the following multi-threaded code segment (in a mix of C and pseudocode), invoked by two processes P1 and P2, and each of the processes spawns two threads T1 and T2: int x = 0; // global Lock L1; // global main() { create a thread to execute foo(); // Thread T1 create a thread to execute foo(); // Thread T2 wait for the two threads to finish execution; print (x);} foo() { int y = 0; Acquire L1; x = x + 1; y = y + 1; Release L1; print (y); } Which of the following statement(s) is/are correct ?

Both T1 and T2, in both the processes, will print the value of y as 1.

At least one of P1 and P2 will print the value of x as 4

Both P1 and P2 will print the value of x as 2.
