    Answer:

    The speed of Alessandra’s motion is 2 ft/s up.

    (C) is correct option.

    Explanation:

    Given that,

    Time = 1 sec

    Height = 2 feet

    We need to calculate the speed of Alessandra’s motion

    Using formula of speed

    v=\dfrac{d}{t}

    Where, v = speed

    d = height

    t = time

    Put the value into the formula

    v=\dfrac{2}{1}

    v=2\ ft/s

    The direction will be up ward.

    Hence, The speed of Alessandra’s motion is 2 ft/s up.

    (C) is correct option.
