A water treatment plant streams temperature, pressure, and flow-rate readings from hundreds of sensors every second. Engineers do not want to define every possible failure pattern in advance; instead they want a model that learns what normal combined sensor behavior looks like and automatically flags any reading pattern that deviates significantly from that learned norm for human review. Which AI capability does this describe?

Short Explanation
Hundreds of sensors streaming numbers every second is too much for anyone to write rules for in advance, nobody can predefine every combination of temperature, pressure, and flow that might signal trouble. So instead of hand-coding failure conditions, the plant wants a model that watches normal operation long enough to learn what typical combined readings look like, and then raises a flag whenever the live data drifts far from that learned baseline. That is the core idea behind spotting the unusual without knowing ahead of time exactly what unusual will look like. The wrong turns here come from picking capabilities built for a different kind of input entirely: sorting pictures into categories needs images, not sensor streams; pulling names and organizations out of text needs written language, not numeric readings; and turning text into spoken audio has nothing to do with watching numbers for a deviation.
Full Explanation
The correct answer is B. A model that learns what normal combined sensor behavior looks like from streaming data and flags readings that deviate significantly from that learned norm, without every failure pattern being defined in advance, is performing anomaly detection. Option A is incorrect because image classification assigns labels to pictures, and the plant's data consists of numeric sensor streams rather than images. Option C is incorrect because named entity recognition extracts people, organizations, and similar entities from written text, which has no role in interpreting temperature, pressure, and flow-rate readings. Option D is incorrect because speech synthesis converts text into spoken audio output, an unrelated capability to monitoring sensor data for unusual patterns. The plant's requirement, letting the system learn a baseline of normal combined readings and surface deviations for human review rather than relying on a predefined list of failure conditions, is exactly the problem anomaly detection is designed to solve, since it generalizes to failure modes nobody explicitly anticipated.
