Final answer:
The normal type of family structure in Canada today is the nuclear family, which consists of one or two parents and their immediate offspring. Correct option is A.
Step-by-step explanation:
In Canada today, the normal type of family structure is the nuclear family. This type of family consists of one or two parents and their immediate offspring. It is the smallest family structure and is commonly found in societies where geographic mobility is valued.
The nuclear family is most common in small-scale foraging societies and industrial/postindustrial and market societies. Although the traditional model of a nuclear family with a two-parent household has become less typical over the years, it still remains the dominant family structure in Canada.
