Question

Which of the following statements regarding the protozoans is correct?

• A. They are unicellular.
• B. They are eukaryotic.
• C. They are heterotrophic.
• D. All of the above.

Answer 1

The correct option is D All of the above.

Protozoans are single-celled (unicellular), heterotrophic (cannot synthesize their own food) eukaryotes. They are more animal-like as they lack a cell wall. They are either free-living or parasitic. They use flagella, cilia, or pseudopodia for the purpose of locomotion.
Hence, all the above statements regarding the protozoans are correct.
So, the correct answer is option D.
