Solution

The correct option is C $1$
Dielectric constant of a medium $K = \frac{ϵ}{ϵ_{o}}$
where $ϵ$ is the permittivity of the medium.
For air, $ϵ = ϵ_{o}$
$⟹$ $K = 1$

The dielectric constant of air is.

The correct option is C 1Dielectric constant of a medium K=ϵϵowhere ϵ is the permittivity of the medium.For air, ϵ=ϵo⟹ K=1

The correct option is C $1$
Dielectric constant of a medium $K = \frac{ϵ}{ϵ_{o}}$
where $ϵ$ is the permittivity of the medium.
For air, $ϵ = ϵ_{o}$
$⟹$ $K = 1$
