Answer
- B Back-to-back testing between the environments, also across many edge cases

Back-to-back testing is especially useful when an ML system moves to another environment, for example from development to production, and you want to compare whether it works the same there. Because very many inputs can be compared, it also finds small deviations with edge cases or unusual inputs.
