A. Extended family
B. Foster family
C. Nuclear family
D. Single-parent family

B. Foster family

The correct answer is B. Foster family.

Explanation: Foster care involves placing children who are unable to live with their birth families into temporary homes with foster families. These children often face difficult circumstances, such as neglect, abuse, or the inability of their birth families to provide for their basic needs. Foster families support these children by providing a safe and nurturing environment until they can be reunited with their birth families, adopted by a forever family, or reach independent living age. The goal of foster care is to ensure the well-being and development of the children and to provide them with stability and the opportunity to find a permanent home. While extended families (A) may sometimes provide temporary care, foster families are specifically trained and certified to provide support to these children. Nuclear families (C) and single-parent families (D) refer to different family structures, but they are not necessarily involved in the foster care system.
