What is the per-channel data rate of the INMARSAT terminal described as Block 6 - HSD 400?

Explanation:
Per-channel data rate is the speed of one single communication channel within a multi-channel high‑speed data link. In Block 6 – HSD 400, the system delivers roughly 400 kbps total by using several channels together, and each channel operates at 64 kbps. That makes 64 kbps the best answer for the data rate on an individual channel. The other options reflect total link rates or different channel arrangements rather than the speed of a single channel within this multi-channel setup.
