Ah, the age-old question of preventing hydrogen embrittlement. I'll go with C - PWHT, because who doesn't love a good heat treatment?

Hmm, I think the answer is D. Gotta use those lower strength steels and throw in some alloying for good measure. Can't forget the tempering either!

Oooh, I know this one! It's C - PWHT. Gotta love that post-weld heat treatment to get that ductility back.

Haha, I always forget which one is PWHT. Is that the one where they put the steel in the microwave to temper it?
