Answer:
b) organisms in Monerans have a well-defined nucleus.is incorrect
Explanation:
Kingdom Protista includes the single-celled (unicellular) eukaryotic organisms (cell containing a nucleus).
The main criteria of the five-kingdom classification were cell structure, body organization, mode of nutrition and reproduction, and phylogenetic relationships.
Blue-green algae (kingdom Monera) and some plant-like protists like diatoms are autotrophic in nature because they prepare their own food through photosynthesis.
The monerans are considered to be the most primitive organisms. These are unicellular prokaryotes that do not have a well-defined nucleus and other membrane-bound organelles
