stack.push(x + 1);
y = stack.top();
stack.pop();
stack.push(x + y);
x = stack.top();
stack.pop();
cout << "x = " << x << endl;
A) x = 4
B) x = 5
C) x = 6
D) x = 9

The code initializes a stack of integers and pushes 6, x (which is 4), and x+1 (which is 5) onto the stack. The variable y is then assigned the top value of the stack (which is 5), and the top two values of the stack (5 and 4) are added together and stored in the stack. The new top value of the stack is then assigned to x (which is 9). Therefore, the output of the code will be "x = 9".
