True because carbohydrates are in the cell membrane.
In this case, the protozoa will be in category B - animal-like protist.
Animals consume other living organisms to obtain energy. Archaea and bacteria are a high level classification of different kinds of microorganisms that include many different subtypes. So these are not appropriate answers as they are not specific enough. Plant-like protists can photosynthesize which these protozoans cannot. Fungus does have similarities with animals in that it consumes living tissue to survive, however animal-like protist is the best fit for this questions.
Fossils should be your answer
Fossils usually are bones, as bones are strong, and can last for long amounts of time without breaking down.
hope this helps
