The kingdoms that include both unicellular and multicellular organisms are Fungi and Protists.
- Protists: This kingdom comprises a diverse group of organisms, including both unicellular organisms (like amoebas and paramecia) and some multicellular forms (like certain algae).
- Fungi: This kingdom mainly consists of multicellular organisms (like mushrooms and molds) but also includes unicellular forms such as yeasts.
In contrast, the kingdom Animalia is primarily composed of multicellular organisms. Therefore, the correct option is Fungi and Protists.
