The correct answer is D.
As more risks are identified, the amount of contingency reserves set aside to cover those risks will increase, not decrease. However, a project on which thorough risk response planning is done is likely to experience fewer unplanned risk events. Those unplanned events would add more cost to the project than would the reserves for identified risks.
