Correct Answer: D
Project Delta should be deferred by management, as it has the lowest return on investment (ROI) among the four competing projects. ROI is a measure of the profitability or efficiency of a project, calculated by dividing the net benefits by the total costs. Project Delta has a net benefit of $100,000 and a total cost of $200,000, resulting in an ROI of 0.5. The other projects have higher ROIs: Project Alpha has an ROI of 1.0, Project Bravo has an ROI of 0.8, and Project Charlie has an ROI of 0.6. Therefore, Project Delta is the least attractive option for reducing overall IT risk, and management should prioritize the other projects instead.
