A conductor with 220 mils of insulation would have an insulation thickness of

Explanation:
Insulation thickness is commonly given in mils, where one mil is one-thousandth of an inch. To convert mils to inches, multiply by 0.001. So 220 mils equals 0.220 inches, which is the same as 0.22 inches. The other options would correspond to different thicknesses (for example, 0.20 inches is 200 mils, 0.25 inches is 250 mils, etc.), but they don’t match the given 220 mils.
