Explanation:

1. Analyze "inmobile": Many protozoa (e.g., paramecia, amoebas) are mobile, so "inmobile" is incorrect.
2. Analyze "eukaryotic": Protozoa are single - celled eukaryotes, meaning their cells have a true nucleus and other membrane - bound organelles. This is a defining characteristic of all protozoa.
3. Analyze "vertebrate": Protozoa are single - celled and lack a vertebral column (a key feature of vertebrates), so this is incorrect.
4. Analyze "autotrophic": Most protozoa are heterotrophic (they obtain food from other sources), while autotrophic organisms make their own food (like plants or some bacteria). So this is not a characteristic of all protozoa.

Answer:

B. eukaryotic
