To decide which is the best out of the three, we need to calculate the return/standard deviation, which would imply the return generated per unit of risk.
We calculated the same and saw that the corporate bond has the highest number and therefore it is the best option and the correct answer is A.
Government bond has the same risk as corporate bond but lower return so C is not correct
Stock has very low risk adjusted return so option D is incorrect
We can make a decision with this much information so option B is incorrect
