Explanation:

• Option A is incorrect because a return objective can indeed be specified as a required rate of return, such as the amount needed to achieve a specific financial goal (e.g., retirement income).

• Option B is incorrect because return objectives must align with the client's risk tolerance. Higher expected returns typically involve higher levels of risk.

• Option C is correct because when setting a relative return objective, the benchmark used should be investable, meaning it can be replicated or tracked in practice. This ensures the objective is realistic and achievable.
