Answer:
The most appropriate kingdom would be Animalia.
The common characteristics of the kingdom Animalia may include:
- The organisms of this kingdom are eukaryotic. Thus, they have a well-developed nucleus and other cell organelles like mitochondria et cetera.
- They are multi-cellular organisms, that is, they are composed of many cells. They may show body organization like cells→ tissues→ organs→ organ systems→ organism
- Unlike plants, they lack chloroplast and cell walls.
- They are usually heterotrophic.
Thus, the cell can be classified as Animalian cell.
