Choose Best/Worst Actions Under Time Pressure

You are 70 minutes into a 90-minute online assessment. Your Pandas pipeline passes the visible sample cases but fails a hidden test. A teammate in the chat offers an unverified 'quick fix'. The instructions caution that incorrect assumptions may invalidate the model. You also need to complete a mandatory post-assessment survey before the deadline. Select the best and worst actions and briefly justify your choices (considering stakeholder impact, risk, and integrity): A) Freeze the current pipeline, document assumptions and edge cases, run the remaining unit tests, and set aside about 8 minutes to finish the survey on time. B) Swap your deduplication logic for the teammate's snippet without understanding it, rerun everything, and skip the survey to spend all remaining time debugging. C) Document the failing test with a minimal reproduction, add guardrails that fail fast on detected anomalies, submit partial functionality transparently, and complete the survey quickly at the end. D) Add more model features to improve visible metrics, ignore leakage warnings, use synthetic data to fill gaps, and delay the survey past the deadline.

Overview: This question assesses judgment and leadership skills in data science—covering risk assessment, stakeholder impact analysis, integrity under time pressure, and dealing with failing tests and input from collaborators—and belongs to the Behavioral & Leadership category.
