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.

I think carbon and hydrogen.
Behavioural genetics is the study of the effects of genes as well as well the environment on the behaviour of the individuals. The scientists who study the Behavioural genetics are known as behavioural geneticists.
In this case Dr. Hakim is studying the influence of genes and the environment on the aggression, which is a kind of behaviour. Hence, Dr. Hakim is a behavioural geneticists, and he works in in the field of behavioural genetics.
