This question comes from the Amateur Extra Exam. Here again we find ourselves in a “its just the rules, sir” situation. The answer comes from Part 97.3, specifically the definitions section. Where the definition of a Telecommand Station is given as:
(45) Telecommand station. An amateur station that transmits communications to initiate, modify or terminate functions of a space station.
So, the answer is B) An amateur station that transmits communications to initiate, modify or terminate functions of a space station
