I agree with C, but isn't it a bit confusing with all the labels?

Nah, it actually decrements the TTL too, right?

Wait, I thought it just forwarded without changing anything?

I feel like the P router definitely does something with the labeled packets, but I can't remember if it just forwards them without any changes.

I practiced a similar question where the P router had to decrement the TTL, so I might lean towards that option.

I remember something about how the P router should forward based on the inner label, but I can't recall the specifics.

I think the P device swaps the outer label before forwarding, but I'm not entirely sure if that's always the case.
