Removing glued PVC fitting from cast iron. Under kitchen sink

[Vikep]

Hi there. I'm doing a simple and minor kitchen remodel myself. I'm pretty handy but am a novice plumber. I'm running into an issue that I can't seem to figure out and don't want to start cutting things before I'm fully informed. I removed the old sink in our kitchen and revealed a PVC drain and trap connected to a cat iron waste line. All but one section of the PVC are glued and the transition from PVC to cast iron looks like a proper fitting but it's glued together with a green colored cement. I want to install a new sink and replace the drain system from the new sink to the waste line.

I feel like I have a couple of options. I could:

A: try to remove the transition fitting from the PVC to the Cast iron. This would be the ideal situation I think as I could start fresh.

B: cut the PVC right after the transition and continue from there

C: try to reconnect the new sink to the existing setup.

I've attached a couple pictures of the whole drain setup and hopefully it helps explain. Thanks in advance!

Sorry the image is upside down. Don't know why it did that

I fixed the upside down pic for you. Sure looks like the last pvc piece is threaded onto the cast iron. Cut all but the last piece of pvc and simply unscrew it and start over.

remove everything..all the way back to the stack.

those 45 offset is illegal, and the reason they were having problems with their sink to begin with

Thanks for the quick replies. Yes Frodo I know nothing about the legality of the pipes here thanks for the info. I'll have to leave that job up to a licensed plumber. Cutting out cast iron is not something I feel great about.

Havasu, in response to you, Yes it does look like that last piece is screwed in but the threads are coated in a green cement. I haven't tried wrenching off that last section of PVC but do you think I can with all that glue in there? I attached a closer look at the last fitting. Not sure why but all the pictures from my phone are posting upside down. Thanks again guys!
