Hollande solution is a modified version of Bouin solution.

• A. Modified version of Bouin solution
• B. Contains formaldehyde and is a noncoagulant fixative
• C. Used only for electron microscopy
• D. It is identical to Bouin

Answer: (A)

Hollande solution is a Bouin-type fixative, meaning it is built on the same base components as Bouin’s solution but with a modification in the formulation. This makes it a distinct preparation rather than identical to Bouin’s solution, while still sharing similar fixation and staining behavior. That’s why the statement describing it as a modified version of Bouin is the best description. It’s not restricted to electron microscopy, and while it includes formaldehyde like Bouin, the defining point is that it’s a modified, not identical, formulation.
