Hmm, I'd say thermal fatigue. The repeated temperature changes can really take a toll on the metal over time.

I'm not sure, but I think it could also be B) Thermal fatigue, as repeated heating and cooling can lead to failure.

Thermal shock, definitely. I've seen this happen when pouring hot water into a cold metal cup. Instant cracking!
