Assuming D (Thunderbolt) as it’s a Apple trademark.

C and D both meet the requirements. B is excluded due to the fact it is not designed to transfer digital video– it can be hacked to do so, though. A is excluded as HDMI is designed to transfer data and video, not power. The power usage in HDMI is 50mA compared to USB (100mA) which is ~10 times closer. So, once again, it’s possible but not designed for. The reason behind removing C is because USB applies to all devices– not just Apple computers. In addition, Thunderbolt is trademarked by Apple.
