Which wire gauge has the smallest diameter in the listed data?

• A. AWG 6
• B. AWG 24
• C. AWG 18
• D. AWG 10

Answer: (C)

In the American Wire Gauge system, a larger gauge number means a smaller diameter. So the thinnest wire corresponds to the largest gauge number. Among the options, the largest number is 24, which means AWG 24 has the smallest diameter in this list. For contrast, AWG 18 is thicker than AWG 24 (though thinner than AWG 6 and AWG 10), so it isn’t the smallest.
