Correct answer: B. Viruses

- B. Viruses

- D. Both A and B
Explanation
According to Dmitri Ivanovsky (1892), the discoverer of the first virus (tobacco mosaic virus), the infectious agent that passed through porcelain filters (which normally trapped bacteria) was described as "soluble living germs."By this, he meant that the disease-causing agent was so small it could pass through bacterial filters, appearing to be a contagious, soluble substance rather than a typical microorganism. Later, this "soluble living germ" was recognized as a virus.

About Biodiversity and Variety of Life
Biological classification uses taxonomic ranks, binomial nomenclature and shared characteristics to organize life into kingdoms. The major groups include prokaryotes, protists, fungi, plants and animals, with comparisons based on cell type, cell wall, nutrition, body organization, reproduction and evolutionary relationships; prokaryotes lack a membrane-bound nucleus.
