Which of the following systems of equations has no solution?

\begin{aligned} 2 x - y + 3 z & = 2 \\ 6 x - 3 y + 9 z & = 4 \\ x + y + z & = 1 \end{aligned}

\begin{aligned} 2 x - y + 3 z & = 2 \\ 6 x - 3 y + 9 z & = 6 \\ x + y + z & = 1 \end{aligned}

\begin{aligned} 2 x - y + 3 z & = 2 \\ 6 x - 2 y + z & = 4 \\ x + y + z & = 1 \end{aligned}

\begin{aligned} 2 x - y + 3 z & = 2 \\ 6 x - 3 y + 9 z & = 6 \\ 4 x - 4 y + 6 z & = 4 \end{aligned}
