        The plane\[2x-(1+\lambda )y+3\lambda z=0\]passes through the intersection of the plane

    A) \[2x-y=0\]and \[y+3z=0\]

    B) \[2x-y=0\]and \[y-3z=0\]

    C)  \[2x+3z=0\]and \[y=0\]

    D)  None of the above

    Correct Answer: B

    Solution :

                    The equation of the given plane can be written in the form\[(2x-y)+\lambda (-y+3z)=0\]which is a plane passing through the intersection, of the plane\[2x-y=0\]and\[-y+3z=0\].
