Yeah, I remember practicing questions about fire classes, and Class D definitely had to do with metals like magnesium.

I’m not confident, but I think Class A is for ordinary combustibles, right? So that can't be it.

I think it's Class D, but I'm not completely sure. I remember something about metals being a separate category.
