Schiff reagent is a reduced solution of which compound?

Explanation:
Schiff reagent is a colorless solution formed by decolorizing basic fuchsin with sulfurous acid. When aldehyde groups are present (as in carbohydrates after oxidation), this reduced fuchsin is reoxidized to a magenta color, allowing PAS staining to reveal structures like glycogen, mucopolysaccharides, and basement membranes. So the compound that Schiff reagent is derived from in its reduced form is basic fuchsin. The other dyes listed are not used to make Schiff reagent.
