The correct option is D All of the above
Unlike the prokaryotic cells which have a single circular naked DNA without any histones (only a few exceptions exist), the eukaryotic cells have a linear DNA which exists in the form of several chromosomes. The DNA is arranged in the form of chromosomes; It starts with wrapping the DNA around histone proteins which are further folded in an ordered fashion to form a compact structure which is the chromosome. Thus, the correct option is D.
