Consider the following two-process synchronization solution.

\begin{array}{|l|l|}\hline \text{PROCESS 0 } & \text{Process 1 }\\ \\ \text{Entry: loop while (turn == 1); } & \text{Entry: loop while (turn == 0);} \\ \quad\text{(critical section)} &\quad \text{ (critical section)} \\ \text{Exit: turn = 1;} & \text{Exit turn = 0; }\\ \\\hline \end{array}

The shared variable turn is initialized to zero. Which one of the following is TRUE?

(A)

This is a correct two- process synchronization solution.

(B)

This solution violates mutual exclusion requirement.

(C)

This solution violates progress requirement.

(D)

This solution violates bounded wait requirement.
