Which wire gauge is the smallest in diameter among common alarm conductors?

Explanation:
In this system, wire diameter gets smaller as the gauge number gets larger. So to find the smallest diameter, look for the highest gauge value among the options. Among common alarm conductors, the thinnest wire in the set is the one with the largest gauge number, which is 28 AWG. That makes it the smallest diameter. The other choices are thicker: 24 AWG is finer than 22 AWG but thicker than 28 AWG, and 26 AWG sits between 24 and 28. This is why the thinnest option is the one with the highest gauge number, not the middle one.
