Answer:

The correct answer will be option-Cells can generate from nonliving matter.

Explanation:

Rudolf Virchow is known for modifying the cell theory proposed by the Schleiden and Schwann in 1839. He added to the existed theory and suggested that all living cell come from the pre-existed cells.

But this hypothesis was disproved after the Miller and Urey performed an experiment in 1953 and demonstrated that cells were originated from the non-living matter present in the atmosphere during primordial time.

This fact disproved the hypothesis of Virchow ans thus is the correct answer.
