The extended family often includes:

The concept of an extended family is characterized by the inclusion of multiple generations living together or in close proximity. This setup typically consists of parents, their children, grandparents, aunts, uncles, and other relatives who share a household or maintain strong relationships. The presence of several generations under one roof not only creates a supportive environment but also fosters cultural traditions and shared responsibilities, contributing to a strong familial bond.

In contrast to the correct choice, the other options illustrate more limited family structures. Immediate relatives only refer to the nuclear family, which consists of parents and their children. Single parents and their children represent another family dynamic but do not capture the essence of the broader extended family. Finally, families with adopted children may still have varying configurations, and the adoption itself does not define the extended family structure. Thus, the correct answer recognizes the inclusive nature of extended families, highlighting the significance of multiple generations living together.
