The correct answer is D) cells can generate from nonliving matter.
The finding that would have disproved Virchow’s hypothesis is "cells can generate from nonliving matter."
We are talking about the hypothesis of German scientist Rudolph Virchow (1821-1902). He was a renown scientist that studied many branches of science such as biology and pathology. Many modern scientists consider his works as fundamental contributions to modern pathology. He established that cells arise from pre-existing cells and he based his investigations on this principle.
