Answer: (C)

Verified step by step guidance

1. Step 1: Begin by understanding the hierarchical structure of biological classification, which includes the following levels: Domain, Kingdom, Phylum, Class, Order, Family, Genus, and Species.
2. Step 2: Recognize that 'Protista', 'Animalia', and 'Plantae' are broad categories used to group organisms based on shared characteristics. These terms are not specific enough to refer to lower taxonomic levels like Phylum, Class, or Order.
3. Step 3: Recall that the Kingdom level is one of the primary divisions under the Domain level in taxonomy. It is used to classify organisms into large groups based on fundamental traits, such as mode of nutrition, cell structure, and reproduction.
4. Step 4: Understand that 'Protista', 'Animalia', and 'Plantae' are examples of Kingdoms within the Eukarya domain. Each Kingdom represents a distinct group of eukaryotic organisms with unique characteristics.
5. Step 5: Confirm that the correct taxonomic level for the terms 'Protista', 'Animalia', and 'Plantae' is Kingdom, as they represent major divisions within the classification system.
