Which of the following indicates that P_i can enter the critical section in Peterson's solution? A) flag[j] == false or turn == i B) flag[j] == true or turn == i C) flag[j] == false or turn == j D) flag[j] == true and turn == j

In Peterson's solution, a process can enter the critical section only when its flag is set to true and it has the turn. In this case, PS1U1B1i has set its flag to true, but it needs to check if the other process (j) has also set its flag to true and if the turn is set to i. If any of these conditions are not met, then it cannot enter the critical section. Therefore, option A is correct as it checks that the flag of the other process (j) is false and the turn is set to i, allowing the process PS1U1B1i to enter the critical section.
