The answer is the third one (C): Protista.

Explanation for each option:

  • Monera: This is not a kingdom of Eukarya. Monera is an outdated classification that referred to prokaryotic organisms, which are not part of the Eukarya domain. It included bacteria and archaea.

  • Plantae: This kingdom consists of multicellular organisms that are primarily autotrophic, such as trees, flowers, and grasses. They are not primarily one-celled organisms.

  • Protista: This kingdom consists primarily of one-celled (unicellular) organisms, although there are some multicellular protists. Protists are a diverse group of eukaryotic organisms that are not plants, animals, or fungi. Examples include amoebas and algae.

  • Fungi: This kingdom includes mostly multicellular organisms, such as mushrooms and molds, although there are some unicellular fungi like yeasts. However, it is not primarily composed of one-celled organisms.

  • Animalia: This kingdom consists of multicellular organisms that are heterotrophic, such as mammals, birds, and insects. It does not primarily consist of one-celled organisms.

In summary, the kingdom Protista is the one that primarily consists of one-celled organisms within the domain Eukarya.
