In the options you provided, "the continuation of traditional gender roles" would best describe an example of cultural divergence, as it signifies a specific cultural practice that may continue separately from evolving societal norms in different regions.
However, if you're looking for an option that more directly indicates divergence, none of the options explicitly capture it perfectly, but "the continuation of traditional gender roles" implies a cultural practice that might be diverging from more modern, egalitarian values.
If you need to choose from the options given, you might select "the continuation of traditional gender roles."
