Final answer:
The correct answer is option C) nuclear family.
Step-by-step explanation:
Abi's family consists of her parents and her younger sister, Kendra, sharing a household and chores. This type of family structure is defined as a nuclear family. A nuclear family typically includes two parents (traditionally a married husband and wife) and their children living in the same household. Contrastingly, an extended family includes relatives such as grandparents, aunts, uncles, and cousins, in addition to the immediate family. A blended family would involve step-siblings, half-siblings, or step-parents as a result of remarriage.
A foster family would consist of a child or children being cared for by people who are not their biological or adoptive parents. In Abi's case, since there is no mention of step-relations, non-biological guardians, or other extended relatives living in the household, the correct answer is C) nuclear family.
