Find the Solution or Solutions, If Any Exist, to the System

Multiple Choice

Find the solution or solutions, if any exist, to the system.
- $$\left\{ \begin{array} { c } 2 x - 6 z - 6 w = - 4 \\x + y + z + 3 w = 2 \\4 x + 2 y - 4 z - 4 w = 0 \\6 x + 4 y - 2 z + 2 w = 4\end{array} \right.$$

A) infinitely many solutions of the form $x = 3 z - 2 , y = - 4 z + 4 , z = z , w = 0$
B) inconsistent system, no solution
C) $x = - 2 , y = 4 , z = 0 , w = 0$
D) infinitely many solutions of the form $x = - 3 z - 2 , y = 4 z + 4 , z = 0 , w = w$
