I'm not sure, but I think it's between A) Transition limit and B) Endurance limit.

The endurance limit makes sense, but I'm also curious about this 'speed limit' option. I wonder if that's a trick question or something?

I agree with Levi, because below the Endurance limit, fatigue will not occur in carbon steel.

Hmm, the endurance limit sounds right to me. I remember learning about that in my materials science class.

I'm pretty sure it's the endurance limit. That's the stress level where fatigue won't occur, right?
