Best answer
The correct choice is (d) Histones

For explanation I would say: Histones are rich in basic amino acid (AA) residues such as lysine and arginine. These two amino acids carry a positive charge at their side chains. Due to this reason, histones are called as the set of positively charged basic proteins.
