I gotta say, Option C is pretty clever. Using the Fn::Split function to extract the region from the StackId? That's some next-level CloudFormation wizardry right there.

Haha, Option D is just plain silly. Dynamically importing the region from Parameter Store? That's like using a sledgehammer to crack a nut. Keep it simple, folks!

Hmm, I'm not sure Option A is the best choice. What if you need to deploy the template in multiple regions? Wouldn't it be more flexible to use a parameter instead?

Option A is the way to go! It's the most straightforward and efficient solution. Why complicate things when you can just use the built-in pseudo parameter?
