Which of the following is NOT a component of Gomori aldehyde fuchsin solution?

Explanation:
The staining solution known as Gomori aldehyde fuchsin is built around three components that work together to highlight elastic fibers. The dye is basic fuchsin, which provides the color. The solution is kept acidic with hydrochloric acid, a condition that helps convert the dye into aldehyde fuchsin so it binds selectively to elastic fibers. Paraldehyde is included to stabilize the solution and act as a preservative, helping the reagent stay effective over time. Methylene blue, on the other hand, is not part of this preparation; it’s a different dye used in other staining recipes or as a separate counterstain in other protocols, but not in Gomori aldehyde fuchsin.
