Solution

The correct option is D I, II, and III
Kingdom Monera includes all prokaryotic forms. Plants (Kingdom Plantae), animals (Kingdom Animalia), and Fungi (Kingdom Fungi) are eukaryotic forms.
Kingdom Protista includes eukaryotic forms which are thought to be the first eukaryotes evolved. Hence, it is considered as a connecting link between kingdom monera and plants, animals, and fungi.
The mode of reproduction in protists is commonly asexual which occurs through fission, budding, sporulation, etc.
Some protists also reproduce sexually by conjugation (a process involving cell fusion) and zygote formation
Eukaryotes are characterized by the presence of a well-defined nucleus and membrane-bound cell organelles.

So, the correct answer is option D.
