Which staining technique is used to visualize candidal hyphae?

Explanation

Among the various staining methods, the Periodic acid–Schiff (PAS) stain is specifically effective for highlighting candidal hyphae due to its ability to detect polysaccharides in fungal cell walls. Other stains like Van Gieson's, Masson's Trichrome, and Toluidine blue are not typically used for this purpose.
