3d Geometry

Let P be the plane passing through the point (1, 2, 3) and the line of intersection of the planes \(\overrightarrow r \,.\,\left( {\widehat i + \widehat j + 4\widehat k} \right) = 16\) and \(\overrightarrow r \,.\,\left( { - \widehat i + \widehat j + \widehat k} \right) = 6\). Then which of the following points does NOT lie on P?
