    C)  Statement I is true, but Statement II is false

    D)  Statement I is false, but Statement II is true

    Correct Answer: A

    Solution :

     As air moves from high to low pressure in the Northern hemisphere, it is deflected to the light. In the Southern hemisphere, air moves from high to low pressure and deflected to the left due to Coriolis force. The Earth's rotation (West to East) deflects the direction of the wind to the right in the Northern hemisphere and to the left in the Southern hemisphere.
