Solution

The correct option is D Monera
R. H. Whittaker proposed the five-kingdom classification, in which the kingdom Monera is considered as the most primitive group. The kingdom Monera includes organisms such as the archaebacteria, bacteria, cyanobacteria (BGA). These organisms are unicellular prokaryotes.
