DVB-S2X improves efficiency by using what?

Explanation:
DVB-S2X boosts efficiency by expanding how data is packaged and protected in transmission. It uses higher‑order constellations, which carry more bits per symbol, together with improved error-correcting codes. This combination lets more data be sent in the same bandwidth while keeping error rates acceptable, yielding greater spectral efficiency. The other options imply no change or worse coding or modulation, which would not lead to the observed efficiency gains.
