Answer:
b. Mainly between the conserved histone folds and the phosphate backbone of the DNA helix.
Explanation:
Histones are proteinous substances that are present in the chromatin of eukaryotic organisms.
The histones help to package or group DNA molecules in eukaryotic organisms into a structure that we refer to as chromosomes.
The contacts between the DNA and the histones of the nucleosome occurs mainly between the conserved histone folds and the phosphate backbone of the DNA helix.
