Which sequence lists the basic taxonomic ranks from broadest to most specific as presented in the material?

• A. Kingdom, Phylum, Class, Order, Family, Genus, Species
• B. Kingdom, Phylum, Class, Order, Family, Species, Genus
• C. Kingdom, Class, Phylum, Order, Family, Genus, Species
• D. Domain, Kingdom, Phylum, Class, Order, Family, Genus

Answer: (A)

The sequence being tested reflects the order of taxonomic ranks from broadest to most specific as presented: Kingdom, Phylum, Class, Order, Family, Genus, Species. This aligns with the standard hierarchy where each step narrows classification, with Species being the most specific category.

In this material, Domain is not included in the basic ranks, so starting with Kingdom is considered the broadest level shown. That makes the sequence that starts with Kingdom and proceeds in the correct order the best choice.

The other options fail because they either swap the relative positions of ranks (placing Class before Phylum, or placing Genus after Species) or they add Domain, which isn’t part of the presented list.
