What is the broadest taxonomic rank mentioned in the material?

Explanation:
Understanding taxonomic hierarchy: Domain is the broadest rank among the options. It sits above kingdom, phylum, and class, grouping life into three large lineages—Archaea, Bacteria, and Eukarya—based on fundamental differences in cellular organization and genetics (notably ribosomal RNA sequences). Within each domain, there are narrower subdivisions like kingdoms (in many groups) and then phyla and classes, but the domain level covers the most diversity and represents the highest level of classification in this scheme.
