Concept:
A
nuclear family is the simplest and most basic form of family structure. It generally includes a married couple and their unmarried children living together in the same household.
This type of family structure is common in modern societies and differs from the
joint or extended family system, where several generations live together.
Step 1: Identify the members of a nuclear family.
- Parents, children, and grandparents – Joint or extended family.
- Parents and their children – Nuclear family.
- Extended relatives living together – Extended family.
- Multiple generations in one household – Joint family.
Thus, the correct answer is
Parents and their children.
