The correct answer is:

Dipolar rotation and ionic conduction; ionic conduction generates stronger heat.

In microwave heating, dipolar rotation refers to the orientation of polar molecules (like water) in an alternating electric field, which leads to the generation of heat. Ionic conduction, on the other hand, involves the movement of charged ions in the material, which can also produce heat. Ionic conduction generally results in stronger heating compared to dipolar rotation.
