    Answer:

    D) Image cannot be seen

    Explanation:

    As we know by lens formula

    \frac{1}{d_i} + \frac{1}{d_o} = \frac{1}{f}

    now we know that

    object is placed at the focal point of lens

    d_o = f

    so we will have

    \frac{1}{d_i} = 0

    so the image will form at infinite

    so image will be at infinite distance from the lens

    so it cannot be seen
