Incorrect Answer.

For the relation parT while (x > 4) x = x - 1; x = 4 to hold, it has to be the case that at any state satisfying T ("true"), if the program in question terminates, then the resulting store satisfies x = 4. This is not the case. For example, if we consider the initial store in which the value stored in x equals 3, then the boolean guard "(x > 4)" of the while-statement evaluates to "false", so the body of that while-statement never gets executed. Thus, the program terminates and does not change the store. In particular, the value stored in x is still 3 which is not equals to 4.
