The approach to handling unethical behaviour ina company should be proactive, which means that steps should me taken before unethic situation happen. But if it happens, you should follow the established protocol to report unethical behaviour.
I would say it would be D or A. Im not quite sure, but you can workout hard without getting injured so my best bet would be D.
D. Use a condom during every sexual encounter
This means do not add in hair if you have already used another product to remove strong curl, make it straight, or "relaxed".
Hope this helps
