If $L _ { 1 }$ is the line of intersection of the planes $2 x - 2 y + 3 z - 2 = 0 , x - y + z + 1 = 0$ and $L _ { 2 }$ is the line of intersection of the planes $x + 2 y - z - 3 = 0,3 x - y + 2 z - 1 = 0$, then the distance of the origin from the plane, containing the lines $L _ { 1 }$ and $L _ { 2 }$ is\\
(1) $\frac { 1 } { \sqrt { 2 } }$\\
(2) $\frac { 1 } { 4 \sqrt { 2 } }$\\
(3) $\frac { 1 } { 3 \sqrt { 2 } }$\\
(4) $\frac { 1 } { 2 \sqrt { 2 } }$
