The following pair of processes share a common variable X. Process A int Y; A1: Y=X*2: A2: X = Y; Process B int Z; B1: Z=X+1; B2: X=Z; X is set to 5 before either process begins execution. As usual, statements within a process are executed sequentially, but statements in process A may execute in any order with respect to statements in process B. How many different values of X are possible after both processes finish executing? O a. three O b. two Ⓒc. four O d. eight
