Which 23 cm frequency is authorized to a Technician Class operator license?
1296 MHz

A person could either memorize that the 23 cm band runs from 1240 MHz to 1300 MHz, and that the whole thing is open to a Technician, or a person could convert the wavelength to a frequency and pick the closest answer.

$ \lambda=\frac{c}{v} $ or $ \text{wavelength}=\frac{\text{speed of light}}{\text{frequency}} $
$ \lambda*v=c $
$ v=\frac{c}{\lambda} $
$ v=\frac{3*10^8}{23cm} $
$ v=\frac{300,000,000}{.23} $
$ v=1,304,347,826.09 $

1,296 MGz is the closest given answer.
