Which of the following is NOT a component of ZAPAM coagulative fixatives?

Explanation:
ZAPAM coagulative fixatives rely on a zinc-containing component to stabilize cellular structure, an alcohol to denature proteins and begin dehydration, and a picric acid component to rapidly coagulate proteins and enhance tissue firmness. Sodium chloride is not used as a fixing agent in this formulation; it serves mainly as a salt to adjust osmolarity, not to promote fixation or protein precipitation. Because fixation with ZAPAM depends on those coagulative actions from zinc, alcohol, and picric acid, sodium chloride does not fit as a component.
