Annie is a meat eater, but has included vegetarian and vegan options on her wedding menu. which kind of response to diversity is this?

I believe it's tolerating type of diversity.

Tolerating types means that you acknowledge there is a difference with others but you choose to live with the difference rather than making an effort to change it. Other examples would be a catholic schools who let their non-catholic students to not follow their religious ceremony.

Annie is a considerate person. Since she invites lots of guests to her wedding, she knows that not everybody wants to eat meat. Since diversity means that some of her friends are vegetarian oder vegan, she wants to have some tasty food for everyone.
