Which of the following describes types of family structures?

The correct choice highlights the various types of family structures that encompass a broad range of household compositions. Nuclear families consist of two parents and their children living together, while extended families include additional relatives beyond the nuclear unit, such as grandparents or aunts and uncles. Single-parent families are formed when one parent raises one or more children, which is increasingly common in modern society. Blended families arise when one or both partners in a couple have children from previous relationships and come together to form a new family unit. Childless families may consist of couples who choose not to have children or are unable to have children for various reasons. This comprehensive categorization reflects the diversity of family dynamics found in contemporary society.

In contrast, the other options present limited or less inclusive definitions of family structures. Describing only nuclear and extended families omits many current realities of family life. The reference to “traditional, modern, and communal families” lacks clear definitions for those terms in the context of family structure. Furthermore, focusing solely on single-parent, blended, and affluent families does not encompass the full spectrum of family types, thus providing an incomplete picture of family structures.
