Suggested Answer: C

I’m a bit confused about the role of responsibility; I thought developers also cared about quality.

I feel like option C makes the most sense, but I also recall discussions about how isolation from the team can help.

I think independent testing is crucial because it helps verify assumptions, but I'm not sure if that's the main reason.
