Guys!
You cant aim to maximize return, because the more risk you are willing to take, the more return you can attain. ‘A ‘is definitely not true; hence it is the right answer. Utility is what investors are after, which varies with each investor. Everyone has different risk return tradeoffs (Indifference curves)

The assumption that they have the same time horizon is part of capital markets theory.

For what its worth, (and I’m sure this is not a unique strategy, but does help with these type of questions) what sometimes helps me on the tricky questions is just eliminating the ones that are true and the one left over is, by default, correct. In this case, B & C are correct assumptions, so A must be the answer. Obviously it helps if you understand why each option is the correct/incorrect choice, but this my help to get through tough questions.
