What is an example of a nuclear family?

A nuclear family is defined as a family unit consisting of two parents and their children living together. The option describing a mother, a father, and a child perfectly fits this definition, as it includes both parents and their immediate offspring. This structure is often contrasted with extended families that may include other relatives, such as grandparents, aunts, uncles, or cousins living in the same household or closely related.

The other possibilities involve family structures that include additional relatives but do not conform to the traditional definition of a nuclear family. For instance, having a grandfather alongside the parents and child introduces an extended family element, while combinations involving friends or extended relatives also deviate from the nuclear family concept.
