Solution

The correct option is D DNA wrapped around histones.
Chromatin is a fibrous heredity material formed by DNA-histone complex. Basically, the DNA-histone thread consists of nucleosome chains. The nucleosome chains are made of histone proteins forming charged cores around which DNA is wrapped.
So, the correct answer is option D.
