The 5 kingdom classification system was proposed by R. H. Whittaker in 1969. This classification divides living organisms into five major kingdoms: Monera (representing prokaryotic organisms), Protista (single-celled eukaryotes), Fungi (fungi such as molds and mushrooms), Plantae (plants), and Animalia (animals). Whittaker's classification was significant because it provided a clearer understanding of the diversity of life forms and their evolutionary relationships.

His system was based on various criteria like cellular organization, modes of nutrition, and reproductive methods, which allowed for a more systematic approach to categorizing the vast array of life on Earth. This classification has been fundamental in the field of biology, influencing how researchers study and understand organisms' interrelationships, ecological roles, and evolutionary history.

So, the correct answer is R. H. Whittaker.
