The correct answer is B. 100.
The dielectric constant of a material is a measure of how much it concentrates an electric field. A material with a high dielectric constant will have a stronger electric field than a material with a low dielectric constant.
In this case, the voltage applied across the ceramic dielectric produces an electrolytic field 100 times greater than air. This means that the dielectric constant of the ceramic is 100.
The other options are incorrect because they do not represent the correct value of the dielectric constant.
