Determine Whether Any of the Lines Given Below Are Parallel

Determine whether any of the lines given below are parallel or identical. $\begin{array} { l } L _ { 1 } : \frac { x - 4 } { 3 } = \frac { y - 9 } { 7 } = \frac { z - 3 } { 2 } \\L _ { 2 } : \frac { x - 3 } { - 3 } = \frac { y - 10 } { - 7 } = \frac { z - 4 } { 2 } \\L _ { 3 } : \frac { x } { 3 } = \frac { y - 2 } { - 7 } = \frac { z - 1 } { - 2 }\end{array}$
$L _ { 4 } : \frac { x - 3 } { 3 } = \frac { y - 10 } { 7 } = \frac { z - 4 } { - 2 }$

A) $L _ { 1 } , L _ { 4 }$ are parallel
B) $L _ { 2 } , L _ { 4 }$ are identical
C) $L _ { 1 } , L _ { 2 } , L _ { 4 }$ are parallel
D) $L _ { 1 } , L _ { 2 }$ are identical
E) $L _ { 1 } , L _ { 3 }$ are parallel
