A. The answer is NO.
In order to get a life insurance policy on someone else, you need to have an "insurable interest" in them, which means their death may cause financial hardship on you therefore you want to receive money for their death. Note that the other person could be a close relative, as the emotional impact of their death could be considered insurable interest.
If you are in a business partnership with someone else, insurable interest is shared between the partners. Since the business would be affected by the passing of any partner, most likely having a financial impact, partners can arrange life insurance protection on each other to mitigate that impact should anyone die prematurely.
