Two processes, P1 and P2, need to access a critical section of code. Consider the following synchronization construct used by the processes :Process P1 :while(true){w1 = true;while(w2 == true);Critical sectionw1 = false;}Remainder Section Process P2 :while(true){w2 = true;while(w1 == true);Critical sectionw2 = false;}Here, w1 and w2 are shared variables, which are initialized to false. Which one of the following statements is TRUE about the above construct?

• A. It does not ensure mutual exclusion
• B. It does not ensure bounded waiting
• C. It requires that processes enter the critical section in strict alternation
• D. It does not prevent deadlocks, but ensures mutual exclusion
