So uh, I know
welcher can be a relative pronoun and I know you can start a relative clause with any Präposition, so that would check it as being a potential Relativsatz. The problem is that it doesn't feel like it's relative to something to me. There's no information available to me (looked on the internet, or in my books) when an indirect question can start with a preposition, so it's a confusing case to me. I do see it being a Subjektsatz but then the Nebensatz has to be of some type on top of that, right?
