Best answer

Correct option (c) the DNA is condensed into chromatin fibre

Explanation

The association of H1 histone with nucleosome indicates that DNA *** in its condensed form. Concept Enhancer In eukaryotes, DNA packaging is carried out with the help of histone proteins. Nucleosome is the unit of compaction. Its core consists of four pairs of histones (H2A, H2B, H3 and H4). The linker DNA, consisting of H1 histone connects two adjacent nucleosomes.

They together constitute chromatosome. It gives rise to a chromatin fibre after further condensation.
