B) Only rupture seems too narrow; thinning affects more than just that.

Definitely C) Metal loss. That's a classic sign of thinning.

I’m leaning towards option C, metal loss, but I wonder if it could also lead to ruptures as well.

I feel like cracks might be a possibility too, but I can't recall if they are directly related to thinning.

I remember practicing a question about failure modes, and I think metal loss was mentioned as a common issue, so maybe that's the right answer?

I think thinning could lead to larger leaks or even rupture, but I'm not entirely sure if that's the most likely outcome.
