Explanation

The answer choices in your question appear to be cut off - all four options only show "1. Acquire sensor data." without their distinguishing subsequent steps. I can't accurately explain why A, B, and C are wrong without seeing what makes them different from D.

Could you paste the full text of each answer choice? They likely differ in how they handle the conditional logic after acquiring the data (e.g., how/whether they check for critical vs. non-critical events before processing).

That said, here's the core concept the question is testing:

The key principle: When most sensor data is non-critical and only changes during critical events, the correct workflow should use exception-based (interrupt-driven) processing - acquire the data, evaluate whether it is critical, then branch: process/alert if critical, discard/ignore if not. Workflows that always process all data equally (regardless of criticality) waste resources and are inappropriate here.

Once you share the full choices, I can give you a precise explanation of each distractor and a memory tip.
