The renewal SRP for subscriptions obtained through the trade-in offers will increase by no more than 5% in 2021, 2023, 2025, and 2027—with no changes in SRP for 2022, 2024, 2026 and 2028.
All customers taking a trade-in will have an ongoing renewal discount price through until 2028. This applies to already discounted subscriptions and subscriptions at SRP that are traded in.
If you have a current discount price, that will remain the same as @AllenJessup said (Thanks!) so basically your option a. is the correct one and you'll keep that price for the 2 year plan that was agreed upon.
