A) Protozoa

Explanation:

Protozoa are the one celled organisms which belong to kingdom Protista and they are animal-like (named as protozoa). Moreover, they host dead organic matter and live in contaminated water.

Spirilla is bacteria which is not animal-like.

Viruses are non-living so they are not organisms.

Fungi is not animal-like or single celled.

for example, no new evidence will demonstrate that the earth does not orbit around the sun (heliocentric theory), or that living things are not made of cells (cell theory), that matter is not composed of atoms, or that the surface of the earth is not divided into solid plates that have moved over geological timescales .
