Question

cilia
○ are made of intermediate filaments.
○ are made of actin and are used to move chromosomes in prokaryotic cells.
○ are made of microtubules and can be found in eukaryotic cells.
○ propel ribosomes through the cytoplasm.

Explanation:

Cilia are hair-like organelles in eukaryotic cells. They are composed of microtubules arranged in a 9+2 structure. Intermediate filaments make up cell structures like nuclear lamina, not cilia. Actin forms microfilaments (used in cell movement like muscle contraction, not cilia structure), and prokaryotes do not have cilia or organized chromosome movement via such structures. Ribosomes are moved by the cytoskeleton's motor proteins, not cilia.

Answer:

are made of microtubules and can be found in eukaryotic cells.
