Which fixative contains acetic acid?

Explanation:
The key idea is that acetic acid is included in some fixatives to help preserve nuclear detail and to soften tissue for better penetration. Zenker's fixative contains acetic acid in its formulation, which enhances preservation of nucleoproteins and nuclear detail while fixing the tissue rapidly. The other fixatives listed are formulated without acetic acid in their standard recipes, so they do not contain acetic acid. Therefore, Zenker's fixative is the one that contains acetic acid.
