Which color is used to indicate the presence of an acid mucopolysaccharide in this image?

Explanation:
Blue indicates the presence of acid mucopolysaccharides because Alcian blue binds to the negatively charged sulfate and carboxyl groups in acidic mucins, producing a blue color. In histology, this blue staining differentiates acidic mucins from neutral ones, which are detected by other stains such as PAS.
