The type of family structure that has a biological parent, a stepparent, and the children of one or both parents is called a blended family. To determine the correct answer, we can eliminate the options that do not match this description.

a. Single-parent family: This type of family structure consists of only one parent and their children. It does not involve a stepparent, so it is not the correct answer.

b. Extended family: An extended family includes relatives beyond the immediate family, such as grandparents, aunts, uncles, and cousins. It does not specifically involve a stepparent, so it is not the correct answer.

c. Foster family: A foster family consists of adults who provide care and support for children who are not their biological or adopted children. It does not necessarily involve a stepparent, so it is not the correct answer.

d. Nuclear family: A nuclear family consists of a married couple and their biological or adopted children. It does not include a stepparent, so it is not the correct answer.

The correct answer is a blended family, which involves a biological parent, a stepparent, and the children of one or both parents.
