Answer:
4. all of the above
Step-by-step explanation:
I think businesses ethics can be all those options, because there's a lot of variation to businesses ethics, so some are the same, some are different, and some can be exactly the same or different by coincidence or on purpose. I hope the answers right, it should be cause there's no law saying that all businesses have to be different, the same, or equal. Although if there the same they could get sued.... I'm sorry if it's wrong but it should be right. Hope it helps!!!
