Let $$A = \left\{ {z \in C:\left| {{{z + 1} \over {z - 1}}} \right| < 1} \right\}$$ and $$B = \left\{ {z \in C:\arg \left( {{{z - 1} \over {z + 1}}} \right) = {{2\pi } \over 3}} \right\}$$. Then A $$\cap$$ B is :

A
a portion of a circle centred at $$\left( {0, - {1 \over {\sqrt 3 }}} \right)$$ that lies in the second and third quadrants only
