Because AC can be stepped up to very high voltage for long‑distance transmission (reducing I²R losses) and easily stepped down again for safe local use. That makes transmission much more efficient and conversion to usable voltages straightforward. (AC generators are also simpler than DC machines with commutators, which was a practical advantage historically.)

So the best choices from your list: "less energy loss during transmission" and "easier to use and convert" (which together explain the more efficient transmission).
