2 idiom errors in (b): * "interact" MUST be paired with "with". "interact between" and "interact among" are unidiomatic. * "among each other" is unidiomatic (as is "between each other"); you should write "among themselves" or "between themselves". but, again, this doesn't work with "interact" anyway, so the issue is moot here.

Interact要求与with搭配
interact with才是正確用法
interact "with" not "among"
