The correct answer is C. Monera.
Bacteria are single-celled organisms that lack a nucleus or other membrane-bound organelles. They are the most diverse group of organisms on Earth, and they can be found in almost every environment on the planet. Bacteria are classified in the kingdom Monera, which also includes archaea.
Animalia is the kingdom of multicellular organisms that are heterotrophic, meaning that they cannot make their own food and must consume other organisms to survive. Animals are characterized by their ability to move, their complex nervous systems, and their ability to reproduce sexually.
Fungi are eukaryotic organisms that are heterotrophic and absorb nutrients from their environment. Fungi are characterized by their cell walls, which are made of chitin, and their ability to reproduce both sexually and asexually.
Protista is a kingdom of eukaryotic organisms that are not plants, animals, or fungi. Protists are a diverse group of organisms that include algae, amoebas, and slime molds. They are characterized by their single-celled or simple multicellular body plans and their ability to reproduce both sexually and asexually.
