Correct answer should be B.
Here's the approximate resistivity of each material:
* Air: 1.3 times 10^{16} - 3.3times 10^{16} Ω.
* Paraffin wax: 10^{13} - 10^{17} Ω.
* Mica: 9 times 10^{13} Ω.
* Mineral oil: Around 10^{13} Ω (for new oil, can decrease significantly with use).
Comparing these values, paraffin wax generally has the highest resistivity, with its upper range potentially exceeding that of air.
