Brittle fracture all the way, baby! It's like the material just decides 'Nope, I'm done!' and *poof*, you've got a pile of metal confetti on your hands.

Hmm, I was leaning towards C. Notch toughness, but I think D is the way to go. Wouldn't want my equipment to shatter like a glass ornament during a simple startup, you know?

Gotta be D, brittle fracture. Temper embrittlement is no joke - it turns the metal into a ticking time bomb waiting to explode during startup!

I'm going with A. Thermal fatigue. Those temperature cycles can really take a toll on an embrittled material, leading to cracking and eventual failure.

Ah, I was debating between B and D, but D makes the most sense. Temper embrittlement really weakens the material's ability to withstand the stresses during startup and shutdown.
