Biological daughters and step daughters?
"Bee" has no meaning to a person who doesn't speak English, because it isn't a word you say everyday. It isn't very important to know what a bee is because it is just a bug, and bugs aren't very important to somebody who doesn't speak English. If people want to learn English, then they would need to know something we say everyday and that is important to everyday life, like food or sleep, not bee.
I think it’s B:)
Hope this helps.
