    A)  (2, 4)                    

    B)         \[(-2,4)\]            

    C)         (2, - 4)                 

    D)         (2, 2)

    E)  (6, 8)

    Correct Answer: A

    Solution :

    Given parabola is \[{{y}^{2}}=8x\]                          ...(i) Line is                    \[y=x+2\]                       ....(ii) On solving Eqs. (i) and (ii), we get Point of contact is (2, 4).
