The association of histone H 1 with a nucleoside indicates

Explanation: 

Histone proteins twist around DNA and form a structure called nucleosome and this structure on further twisting form chromatin fibre.

DNA will be in its condensed form when histone is associated with nucleosomes.

So, the association of histone with a nucleoside indicates the DNA is condensed into a chromatin fibre i.e. Option D is correct.

Final answer:

 Hence, option D is correct i.e. the association of histone with a nucleoside indicates the DNA is condensed into a chromatin fibre.
