Answer: D - The two main iron hematoxylin solutions are Weigert’s and Cole’s hematoxylin solution.
Iron hematoxylin is a ferric salt used to ripen hematoxylin. All the other choices are correct about iron hematoxylin except for the statement that the two main iron hematoxylin solutions are Weigert’s and Cole’s hematoxylin solution. Cole’s hematoxylin is not an iron hematoxylin solution instead it is a type of alum hematoxylin solution. The two main iron hematoxylin solutions are Weigert’s and Heidenhain’s solution.
