And yet, you still don't understand a single thing, and just want to argue. Which seems to be common for you, based on your comment history.

B) the most recent Framework laptop is Thunderbolt certified and tested, so your USB-C ports will support Thunderbolt.
If that simplification isn't enough for you, maybe avoid more technical communities. Just stick to TomsHardware.
