the circles labeled Canis represent all members of the genus Canis, and the circles labeled familiaris represent all members of the species familiaris. Which arrangement of circles best illustrates the relationship between the genus and species of Canis familiaris, the domestic dog?

The best arrangement of circles to illustrate the relationship between the genus Canis and the species familiaris (domestic dog) would be two circles nested within each other, with the larger circle representing the genus Canis and the smaller circle inside representing the species familiaris. This arrangement would show that all members of the species familiaris are also members of the genus Canis, but not all members of the genus Canis are part of the species familiaris.
