The correct answer is C. Autotrophs
Explanation:
In biology, a protist is a type of organism that cannot be classified as a plant, fungus or animal but whose cells contain a nucleus and therefore are classified as eukaryotic. Additionally, protist organism can be plant-like organisms, fungus-like organisms or animal-like organisms depending on whether they share certain features with animals, plants or fungus. In the case of plant-like protists, these are usually unicellular organisms that obtain energy from photosynthesis as plants and therefore they are mostly autotrophs as they do not feed on other organisms to obtain energy but produce it.
