prevailing risk-free rate is 3%.

What is the answer to this question?
For this question I have seen 2 answers. So im not sure whats right.
Answer 1:
The most relevant figure is (a) that reflects the risk-return characteristics of stock A and stock B. an effective frontier is called relationship between risk (standard deviation) and expected return. The shape of risk-return features is curved because for each incremental risk incurred there are raising marginal returns. Therefore, for each unit of risk, the standard deviation applied to the portfolio provides an extremely low amount of return. Also we can see that the SD of stock B is higher than that of A.
Figure b) is incorrect because the returns don’t rise in proportion to the risk assumed.
Figure c) is incorrect since both stocks stock A and stock B are risky, and thus a finite return cannot occur at standard deviation = 0
Answer 2
Answer - Graph B
Correlation = Covariance / (Standard deviation of A x Standard deviation of B)
Correlation = 0.0014 / (0.032 x 0.044)…

If Sharon were risk neutral, which investment would she select? Explain why. b. If she were risk averse, which investment would she select? Why? c. If she were risk seeking, which investments would she select? Why? d. Suppose a fourth investment, W, is available. It offers an expected return of 18%,and it has a standard deviation of 9%.
