A.

The question pertains to maintaining acceptable risk levels after implementing appropriate controls. The objective is to ensure that the risk levels do not increase beyond acceptable limits over time. The best option to achieve this objective is periodic reviews of changes to the environment.

Option A, frequent assessments of inherent risks, may not be necessary if the risks have been mitigated to an acceptable level with appropriate controls. Assessing risks frequently may lead to overanalysis and waste of resources.

Option C, periodic cost-benefit analyses of the implemented controls, is a good practice but may not directly contribute to maintaining acceptable risk levels. Cost-benefit analyses are used to evaluate the efficiency of controls, and they help determine whether the benefits of a control outweigh its costs. They are not directly related to maintaining acceptable risk levels.

Option D, frequent assessments of risk action plans, may be necessary in case there are changes in the environment, but it may not be the best option. It is important to have a plan to mitigate risks, but if the risks have been mitigated to an acceptable level, frequent assessments of risk action plans may not be necessary.

Therefore, the best option to maintain acceptable risk levels is periodic reviews of changes to the environment. This ensures that any changes in the environment that may affect the risk levels are identified and appropriate measures are taken to maintain the acceptable risk levels.
