The relative permittivity has the following units

The correct answer is: D. no units

Relative permittivity is a dimensionless quantity that is used to compare the permittivity of a material to the permittivity of a vacuum. It is denoted by the Greek letter $\epsilon_r$. The permittivity of a vacuum is a fundamental constant of nature, and it is denoted by the Greek letter $\epsilon_0$. The permittivity of a material is given by the equation:

$$\epsilon = \epsilon_r \epsilon_0$$

Therefore, the relative permittivity is a dimensionless quantity.

Option A is incorrect because the units of farad per meter (F/m) are the units of permittivity.

Option B is incorrect because the units of meter per farad (m/F) are the units of
