Which term best describes single-celled, microscopic organisms with eukaryotic cells?

Explanation:
Single-celled, microscopic organisms with eukaryotic cells are protists. They have a true nucleus and membrane-bound organelles, which distinguishes them from bacteria (prokaryotes) and from non-cell things. Protists include a wide variety of organisms like amoebae, paramecia, and many algae, all grouped together in traditional classifications as the Protista kingdom. The other options aren’t organisms with cells: a bacteriophage is a virus, a spore is a reproductive unit, and chitin is a structural material.
