D.
Absence-of-errors fallacy
Suggested answer: A

Explanation:

Defect clustering is the phenomenon that a small number of modules contain most of the defects detected. This principle suggests that testing should focus more on the areas where defects are more likely to occur, rather than spreading the testing effort equally across all modules. Therefore, in the next test cycle, the team should allocate more resources to test the module that had most of the critical bugs.
