Answer:
The correct option is B.
Explanation:
Risk aversion is a situation where investor like returns and dislike the risk. The higher the risk, higher the expected return an investor will demand.
In this situation, will look at the standard deviation (SD). The larger the SD, it states that outcome will be dispersed widely and smaller SD, states that the outcome or result will be more tightly cluster around the expected value. So, because of this will be choosing the Stock B for isolation and Stock A for portfolio which well diversified.
