Suppose threads A and B are attempting to lock at the same time. Assume that there is a single shared variable. Let the value of 0 mean that no object is in the CS. Assume that a value of 1 in this variable indicates that A is entering/is in the CS and a value of 2 in the same register indicates that B is entering/is in the CS. Assume that A and B both read the register, initially 0, and are about to update them. Suppose A updates the register to 1. What would be the result? A. A will enter the CS.
B. The two threads will deadlock.
C. B will wait for A to complete the execution of the CS.
D. B will eventually obliterate the value written by A.
E. The lock object will be in an inconsistent state.
F. Both A and B could be in the CS at the same time.
