A light ray emits from the origin making an angle $30 ^ { \circ }$ with the positive $x$-axis. After getting reflected by the line $\mathrm { x } + \mathrm { y } = 1$, if this ray intersects x-axis at Q , then the abscissa of Q is\\
(1) $\frac { 2 } { ( \sqrt { 3 } - 1 ) }$\\
(2) $\frac { 2 } { 3 + \sqrt { 3 } }$\\
(3) $\frac { 2 } { 3 - \sqrt { 3 } }$\\
(4) $\frac { \sqrt { 3 } } { 2 ( \sqrt { 3 } + 1 ) }$
