Holland's solution is a modification of Bouins. Which fixative is Bouins modified from?

Explanation:
Bouin’s fixative was developed as a modification of an earlier formalin-based fixative known as Hollande’s solution. Bouin’s combines picric acid with formalin and acetic acid, which gives very good tissue preservation and particularly strong nuclear detail. The addition of picric acid to the base formalin-acetic acid mix is what distinguishes Bouin’s from a simple formalin fixative. Among the given options, the idea to trace Bouin’s lineage points to Hollande’s solution as the predecessor, rather than the other listed fixatives.
