Answer
- D In canary testing, real users receive responses from the new model; in shadow testing, they do not
Explanation
In canary testing the updated model is released to a small subset of production traffic, for example 5% of users, who therefore receive responses from the new model. In shadow testing, both models receive the same requests, but the live responses still come only from the current model.
