Which acronym expands to Automatic Temperature Controls?

• A. Air Temperature Controls
• B. Automatic Telemetry Circuit
• C. Automatic Thermal Circuit
• D. Automatic Temperature Controls

Answer: (B)

Acronyms are built from the initial letters of the words in a phrase, so the expansion of an acronym is the exact full phrase it represents. For Automatic Temperature Controls, the three words start with A, T, and C, which gives the acronym ATC. The phrase that ATC expands to is “Automatic Temperature Controls.”

Among the options, the one that matches that expansion is the phrase itself, “Automatic Temperature Controls,” since the other options differ in the middle word (Temperature vs Telemetry vs Thermal). So the correct understanding is that the acronym ATC stands for Automatic Temperature Controls.
