Final answer:
In Wodaabe society, the marital practice most commonly observed is polygyny, where a man has multiple wives.
Step-by-step explanation:
In Wodaabe society, men are often regarded as the more beautiful and delicate sex, while women are seen as more dominant and pragmatic. This presents a unique contrast to many other cultures where women are typically focused upon for their beauty and men for their strength. Within such a societal structure, the common marital practice that is observed in the Wodaabe and similar cultures across Central Africa is polygyny. This is a form of polygamy where a man has more than one wife at the same time.
Polygyny is widely practiced in regions where traditional beliefs permit such marriages, and often, the husbands in these polygamous relationships are older, wealthy, high-status men. It is important to note that while polygyny is accepted in many cultures globally, the majority of people do not practice it. In the specific case of the Wodaabe society, the most accurate answer to the student's question is d) polygyny.
Answer: d) polygyny
