Eukaryotic chromosomes:
a. may occur as chromatin.
b. contain histones responsible for packaging DNA to fit into a small space.
c. consist of both DNA and protein.
d. all of the choices are correct.
e. only A and B are correct.

I think it is: C

Consist of both DNA and Protein

Explanation:

The reason why i say C is because Eukaryotic chromosomes consist of a DNA-protein complex that is organized in a compact manner which permits the large amount of DNA to be stored in the nucleus of the cell. The subunit designation of the chromosome is chromatin. The fundamental unit of chromatin is the nucleosome.
