The Five Kingdom system of classification suggested by R.H. Whittaker is not based on:

  1. A
    Presence or absence of a well-defined nucleus.
  2. B
    Mode of reproduction.
  3. C
    Mode of nutrition.
  4. D
    Complexity of body organisation.

Solution & Step-by-step Explanation

Whittaker's Five Kingdom classification (1969) was based on:Cell structure (Prokaryotic/Eukaryotic)Body organization (Unicellular/Multicellular)Mode of nutrition (Autotrophic/Heterotrophic)Mode of reproductionPhylogenetic relationshipsPresence or absence of a well-defined nucleus is the primary criterion for Kingdom Monera (prokaryotic), but the question refers to the overall system criteria. Mode of reproduction, nutrition, and complexity were key pillars. Note: In some interpretations, "Presence/absence of nucleus" is considered a sub-point of cell structure, but "reproduction" is specifically cited in textbooks as a primary criterion.
