Answer:
A. Protists are more primitive than land plants and animals
Explanation:
Kingdom Protista is a kingdom that consists of one cell or many cells and has a nuclear membrane (eukaryotic organisms) and single cell.
Protists can be grouped into three parts which resemble animals (protozoa), resemble plants (algae) and resemble fungi. Most Protists live in water, because they do not have a barrier to protect their bodies from dry weather.
Kingdom Protista is a simple kingdom because it is only composed of one cell so that it can be grouped in its own kingdom. But there are also multicellular ones but still very simple compared to other
The characteristics of protists are as follows:
1. Unicellular organism (single-celled)
2. Eukaryotic (has a nucleus membrane)
3. Live solitary (alone) or colonize.
4. Generally can not make their own food (heterotof)
5. Live free, saprophytic and parasitic.
6. Can form cysts to survive.
From the characteristics mentioned above, it can be concluded that protists are 1-celled creatures so that they are more primitive than multicellular land plants and animals. Then in choice C. it is said that some protists are eukaryotic. Even though all protists are eukaryotic.
So the choice of the most appropriate answer is A. Protists are more primitive than land plants and animals
