The correct option is A Cellular Pathology
Rudolf Virchow was a German pathologist. In 1858, he published his classical book "Cellular Pathology". In this book, he asserted that functional unit of life, the cells were the primary sets of disease and cancer. He gave the idea that new cells arose from pre-existing cells in diseased and healthy tissues. The statement Omnis cellula e cellula refers that every cell derived from pre-existing cells. Thus, the correct answer is option A.
