The correct option is C Nucleic acids, histone and non-histone proteins.
Chromatin material is made up of nucleic acids like DNA and proteins. The proteins present in chromatin are of two types: histone and non histone proteins. The histone proteins are rich in basic amino acids like lysine and arginine and are present as components of nucleosomes. The histone proteins form the nucleosome core around which the DNA molecule is wound. There are several other proteins associated with chromatin material. They are called non histone proteins.
