Answer:
B. Fathers are used to having total authority over choosing their children's spouses.
Explanation:
In the passage, Nnaemeka expresses that his father is unhappy that he was not the one to arrange the marriage to Nene. To Nene from the city of Lagos and "cosmopolitan atmosphere" the idea of arranged marriage obviously pretty foolish, and somewhat of a joke.
However, it proves the patriarchal values and ideas that still run in the rural societies of Nigeria. In those societies, fathers are still the ones to arrange and bless the marriages, and they want to decide from which part of the society the bride of their son comes. This is the obvious example of patriarchy.
