Solution

The correct option is B Histone protein and DNA
A nucleosome is a basic unit of DNA packaging in eukaryotes, consisting of a segment of DNA wound in sequence around eight histone protein cores. This structure is often compared to thread wrapped around a spool. Nucleosomes form the fundamental repeating units of chromatin, which is used to pack the large eukaryotic genomes into the nucleus while still ensuring appropriate access to it.
