  1. 50 MHz ✔
  2. 440 MHz
  3. 1296 MHz

Why: RF exposure limits vary with frequency because the body absorbs RF energy differently across the spectrum. Among these choices, 50 MHz has the lowest permitted exposure level.

Huh, didn't know that: A lower exposure limit means less field strength or power density is permitted.

The dad joke
Fifty megahertz kept a low profile because its limit was lowest.
