Final answer:

The four phyla of animal-like protists are Amoebozoa, Apicomplexa, Ciliophora, and Zoomastigina, which are all single-celled eukaryotes with traits similar to those of animals.

Step-by-step explanation:

The four phyla of animal-like protists, also known as protozoa, are Amoebozoa, Apicomplexa, Ciliophora, and Zoomastigina. These phyla are characterized by single-celled eukaryotic organisms that share some traits with animals, such as movement and heterotrophy. Among them:

  • Amoebozoa are known for their ability to form pseudopodia for movement and feeding.
  • Apicomplexa includes parasites with complex life cycles, such as those causing malaria.
  • Ciliophora are covered with cilia that they use for movement and feeding.
  • Zoomastigina (also known as Kinetoplastids), which use flagella for movement.

Therefore, the correct answer to the student's question is option a) Amoebozoa, Apicomplexa, Ciliophora, Zoomastigina.
