    Answer:

    The correct answer will be “2 m“.

    Explanation:

    As we know,

    ⇒  \frac{Mirror's \ size}{Body's \ height} =\frac{1}{2}

    Now,

    ⇒  Size \ of \ a \ mirror = \frac{n}{2}

    Then,

    ⇒  Size \ of \ mirror = \frac{4}{2}

    ⇒                            =2 \  meter
