To solve this question, the user needs to know the order of operations in C programming and the difference between pre-increment and post-increment operators.

First, let's break down the expression x = 0 - (++y) + z++:

1. ++y is a pre-increment operator, which means it increments the value of y by 1 before the value is used in the expression. So, y becomes 2.
2. z++ is a post-increment operator, which means it increments the value of z by 1 after the value is used in the expression. So, z remains 5 in this expression.
3. The expression inside the parentheses is evaluated first, so ++y is evaluated to 2.
4. Next, the multiplication and division are evaluated from left to right, but there are none in this expression.
5. Finally, the addition and subtraction are evaluated from left to right.

So, 0 - (++y) evaluates to -2 and z++ evaluates to 5, therefore the whole expression evaluates to -2 + 5 = 3.

Therefore, the correct answer is:

The Answer is: B. x = 3, y = 2, z = 6
