In biological classification, phylum is the rank that is

• A. 2nd most general below kingdom and above class
• B. 2nd most specific below species and above family
• C. In the middle between class and family
• D. The most general

Answer: (A)

Taxonomic ranks go from broad to specific, and phylum sits just below the broadest rank (kingdom) and above class. That placement makes it the second-most general level in this hierarchy. For example, the kingdom Animalia contains the phylum Chordata, which in turn contains the class Mammalia, illustrating the order from broad to more specific. This is not the second-most specific (that would be the rank just above species, which is genus), nor is it the middle between class and family (that position is the rank of order), and it isn’t the most general (the top level is domain or kingdom).
