As we have discussed in Packaging of DNA Helix in Eukaryotes -  

Core histones are H2A, H2B, H3, and H4, where two H3/H4 dimers (H3 and H4 bound together) and two H2A/H2B dimers (these two bound together) form the histone octamer. DNA wrapped around the octamer forms the nucleosome.
Hence, the correct option is (d).
