Answer:
B; A.
Step-by-step explanation:
A minimizer of risk is going to pick stock B for the following reason, it has the lowest standard deviation. this measures the risks facing this investor. For a well diversified portfolio this minimizer of risk is going to go for stick option A. the reason is that, it would add lowest risk. A well diversified portfolio investor is not going consider standard deviation due to things that are of irrelevance like unsystematic diversifiable risk.
If you are a strict risk minimizer, you would choose Stock B if it is to be held in isolation and Stock A if it is to be held as part of a well-diversified portfolio.
thank you!
