D. Low level Air magic makes good SCs as well. Mist Form and Mirror Image can't be replicated by items, so casters who do Air instead of Water have the best of both worlds since the good Water magic can be gained by items.

Chain Mail of Deception grants Mirror Image. There's no item that grants Water Shield, and whether +4 defence is better than Mistform depends from the situation even though Mistform is generally more useful.
