Protozoa is one the diverse groups of single celled eukaryotic organisms, which belong to the kingdom Protista.
The organisms in this kingdom are are basically single celled (that is made up of single cell) and exist separately as well as in the form of aggregates (forming colonies).
Example of Protozoa- Amoeba, Paramecium, Euglena.
Mushrooms belong to the kingdom Fungi.
Fungi is a kingdom of eukaryotic, mostly multi-cellular, non- photosynthetic, heterotrophic organisms.
Most of these organisms grow as tubular structures, known as hyphae, which collectively forms a mycelium ( vegetative part of fungus).
Thus, option A) Mushrooms is the right answer.
