The correct answer, which identifies a family structure emphasizing the roles of both grandparents and parents, is the extended family. This type of family includes not just the nuclear members (parents and children) but can also encompass other relatives such as grandparents, aunts, uncles, and cousins, typically living together or in close proximity. The extended family is significant in many cultures, as it provides support and resources across multiple generations, fostering stronger familial ties and a shared sense of responsibility.
In contrast, the single parent family consists of one parent raising their children, which does not include the grandparents or emphasize their role. A patrifocal family focuses on the father as the central authority figure and may not necessarily include extended relatives. Similarly, a matrifocal family places emphasis on the mother, again lacking the broader inclusion of grandparents and other relatives. Thus, the extended family structure distinctly captures the collaboration and influence of both grandparents and parents working together in family life.
