Solve the equation for y

Which equation is equivalent to the equation below, when solved for y?
                                             2(x + y) - z = 2x + z

A.)  y = 1
B.)  y = z
C.)  y = 1 + 4x
​D.)  y = z + 4x

---

2(x + y) - z = 2x + z
2x + 2y - z = 2x + z   {used distributive property}
2y = 2z   {subtracted 2x and added z to each side}
y = z   {divided each side by 2}

B.)  y = z
