Answer
- D With static drift testing, which statistically compares distributions of inputs and predictions
Explanation
Dynamic drift testing needs feedback from users that shows what is currently right. Static drift testing works without it: it only compares how inputs and predictions were distributed earlier and now, for example with the Kolmogorov-Smirnov test. If a distribution differs markedly, that is a sign of drift.
