The correct answers are "order; no; order; plant species A and plant species B".
Explanation:
Species are categorized in different taxonomic ranks according to physical and genetic features that establish the degree of similarity between species. For instance, two species that are in the same order have a more recent common ancestor than two species that have the same class. Also, two species that have the same genus share the other taxonomic ranks that are in an upper section. In this case, two plants in the same family are in the same order (the next taxonomic rank) however, two plants that are in the same order not necessary are in the same family.
