    C)  Statement I is true but Statement II is false

    D)  Statement I is false but Statement II is true

    Correct Answer: A

    Solution :

     Tides are rise and fall of sea levels caused by the combined effect of the gravitational forces exerted by the moon and the sun and the rotation of the earth because the Earth rotates once in about 24 hours with respect to the sun. The tidal range is not constant but changes depending on where the sun and moon are.
