The correct option is B eye
The center point around which the whole cyclone tends to rotate is known as the eye of the cyclone. This is a low pressure region, due to which more air rushes to the centre of the storm but, starts to swirl due to the rotation of the Earth.
The eye walls are rings surrounding the eye of the cyclone which are very severe and rapidly moving.
Rainbands are the bands of heavy convective showers that shower inward towards the eye of the cyclone.
