Multiple Choice

Bouin solution contains picric acid, formaldehyde, and hydrochloric acid.

Explanation:
Bouin's solution is a fixative composed of picric acid, formaldehyde, and acetic acid. Hydrochloric acid is not part of Bouin's formulation. The acetic acid helps preserve nucleic acids and improves nuclear detail, while picric acid provides rapid fixation and tissue hardening, and formaldehyde cross-links proteins to preserve structure. Because hydrochloric acid isn’t included, the statement is not correct.
