The correct option is C Monera
Eukaryotes
are the organisms which have membrane bound cell organelles as well as membrane
bound nucleus. All the kingdoms except kingdom monera are eukaryotes. Monera is
a kingdom of prokaryotes. It includes the most primitive forms of life which
developed from an early stock called progenote. Being the earliest forms of
life, monerans are adapted to all types of habitats. Population wise they are
the most numerous of all organisms. They are found everywhere, wherever organic
matter can be present or can be supported. They have very little morphological
differentiation. Archaebacteria and eubacteria are the two major groups of
monera.
