B) DNA with H1 only
C) the 10-nm chromatin fiber
D) the 30-nm chromatin fiber

The 30-nm chromatin fibers are looped into domains by the help of scaffolding, forming looped domains or chromatin domains. The DNA wrapped around nucleosomes (10-nm chromatin fiber) is not involved in the formation of looped domains, and neither is the presence of H1 histones. DNA without attached histones does not exist in eukaryotic cells, and even if it did, it would not play a role in the formation of looped domains.
