Scrum effectively limits the risk of unknowingly doing something wrong by a) Having a detailed and extensive risk management plan. b) Having multiple checkpoints and a thorough review by senior management at those checkpoints. c) Using short iterations called Sprints.

C) Using short iterations called Sprints. Near the end of each Sprint, the team will get feedback on their product demonstration from the stakeholders and users to understand if their work was worthwhile. If the work outcome is identified as a waste, the cost spent is limited only to that of the weeks incurred in the Sprint. This feedback is a control and can be used to plan the next Sprint. In other words, the risk of pursuing a wrong direction is limited to the cost of one Sprint. Correct answer is ‘c.’
