Mallory PTAH stain is what type of stain?

Explanation:
Mallory PTAH stain is an example of a polychromatic staining technique. It uses phosphotungstic acid with hematoxylin to produce several distinct colors in different tissue components, so nuclei, muscle fibers, and fibrin can be distinguished by color. Monochromatic stains color most structures in one color, and a dichromatic stain shows two colors; PTAH’s multiple color contrasts make it polychromatic, which is why this option is correct.
