Step-by-step explanation:
The correct answer is B. Extended families.
Extended families often include grandparents, uncles, aunts, or other relatives who live close to the parents and children, making it possible for family members to share resources. An extended family is a household that goes beyond the immediate family to include other relatives such as grandparents, aunts, uncles, and cousins. This type of family may involve multiple generations and commonly shares economic and social support, which is particularly evident in agricultural societies or among families going through transitions such as job changes or economic recovery.
