Chloride stress corrosion cracking, no doubt about it. Although, if I had a nickel for every time I saw that on an exam, I'd have enough to buy the entire stainless steel industry a round of drinks.

Leak can occur? Really? That's like saying 'water is wet' as an answer choice. I'm starting to doubt the competence of the exam writer here.

Chloride stress corrosion cracking for sure. I'd recognize that one anywhere, even with my eyes closed. Or maybe I'd just have to sniff the solution. Mmm, the sweet smell of chloride...

Sulphide stress corrosion cracking? Are you kidding me? This is clearly a chloride issue. I hope the exam doesn't get any more 'basic' than this.

I think leak can occur as well, so maybe B) is also a valid answer.
