Solar flares do not affect Earth's rotation or axis, so Statement II does not explain Statement I. However, polar ice melt does cause a shift in Earth's rotation and axis by redistributing mass from the poles to the equator, which affects Earth's moment of inertia and rotational speed. Therefore, only Statement III explains Statement I.
