Answer:
Having one or more than one eukaryotic cells.
Explanation:
The domain Eukarya consist four kingdoms, which are Protista, Plantae, Fungi, and Animalia. All organisms that belong to domain Eukarya have eukaryotic cells, having membrane-bound cell organelles, such as nucleus, mitochondria, and chloroplasts.
These organisms may be unicellular (such as protists or some fungi) or multicellular (such as plants and animals), due to presence of one or more than one cells, respectively.
Thus, the correct answer is 'having one or more than one eukaryotic cells.'
