This question reminds me of a practice quiz where we discussed root weld sizes. I might lean towards that option.

I feel like the root face is a possibility too, but I need to double-check my notes on that.

I remember something about groove weld sizes, but I can't recall if that's what this is referring to.

I think Item#1 might be the root opening, but I'm not entirely sure. It looks similar to what we practiced in class.

I feel good about this one. The root opening is the space between the two pieces of metal that needs to be filled by the weld, so A is the correct answer.

Hmm, I'd say B, but only because I'm feeling a bit rootless today. Groove weld size for the win!
