Celestine blue
An oxazine dye used as an alternative to iron hematoxylin nuclear stain is Celestine blue. It produces a strong and precise nuclear stain that is resistant to decolorization by succeeding acid stains and solution. Celestine blue forms a strong staining lake with iron alum, acting as a mordant to bind hematoxylin. All the other choices are not used as an alternative to iron hematoxylin nuclear stain.
