Column A and Column B rightly matched

1. family: a group of closely related genera

2. genus: a group of closely related species

3. kingdom: a group of closely related phyla

7. domain: the largest of the classification groups - with three in total

Explanation:

Column A consists of key terms used in the classification of living organisms, while Column B consists of the description of each of the key terms.

The scientific method of classification of living organisms is done in levels, and this study is referred to as Taxonomy. Each level of classification is called a taxon.

The broadest taxon is the domain. All living organisms falls in three domains named Archea, Bacteria and Eukaryote

Within the each of the taxon, there are taxonomic levels ranging from kingdom contains phyla (singular is phylum) class, order, family, genus, and species.

Kingdom --> Phylum --> Class --> Family --> Genus --> Species
