Coming from the prefix "tele" (distant) and the suffix "metry" meaning "the process, art, or science of measuring", telemetry is no more than simply "distance measurements".
Hint: a meter is a unit of measurement

FCC 97.3(a)(44) Telecommand station. An amateur station that transmits communications to initiate, modify or terminate functions of a space station.
Tip - The only answer that contains the words “space station”
Tip2 - A “telecommand” station must be making commands. The correct answer is the one that includes a list of potential commands, “initiate, modify or terminate”.

There are no specific requirements for a balloon beyond those for any aircraft. Therefore like any amateur station, the balloon-borne station must identify with its call sign.

§97.215 Telecommand of model craft.
(c) The transmitter power must not exceed 1 W.
Hint: model craft are nearby and usually line-of-sight, so only low power is needed.
