Question

Quizplus · Accepted Answer

Over the years, classification systems for living things have undergone significant changes. In the past, organisms were classified as either animal or plant. Later, a five-kingdom system was developed, which recognized Monera, Protista, Fungi, Plantae, and Animalia. However, within the last 30 years, the three-domain system, which recognizes Archaea, Bacteria, and Eukarya, has become the preferred classification system. Therefore, option C is the correct answer as it reflects the current classification system. The other options do not accurately represent the evolution of the classification system over time.
