    Answer : Option C

    Explanation :

    A hurricane acquires its spin from the Coriolis effect. When strong air currents (that result in hurricanes, etc.) move above the faster-moving equatorial regions, they get 'pulled' in the direction of Earth's spin, thus veering off from an otherwise straight path. The diameter of a hurricane is never below 150 km.
