Answer:
The correct answer would be phyla; divisions.
In taxonomic classification, the term phylum is used to denote the taxonomic rank present above the class and below the kingdom. it is mainly used in the zoological classification.
The term division is used as equivalent to the phylum and is used specifically for plants classifications.
For example, Acanthocephala, Annelida, Arthropoda, Chordata, et cetera are some phyla used in animal classification. bryophyte, Charophyta, Chlorophyta et cetera are some divisions used in plant classification.
