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.
mid-oceanic ranges I believe.
