Assertion :The dielectric constant is sometimes called relative permittivity or specific inductive capacity Reason: In the centimetregramsecond system the dielectric constant is identical to the permittivity.

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
Assertion:
The
linear permittivity of a homogeneous material is usually given relative to that
of free space, as a relative permittivity εr (also called dielectric
constant although this term is deprecated and sometimes only refers to the
static, zero-frequency relative permittivity). The actual permittivity is
then calculated by multiplying the relative permittivity by ε0:
Reason: In
the centimeter-gram-second (CGS) system, the value of the permittivity of
free space ε0 is chosen arbitrarily to be 1. Thus, the permittivity ε
and the dielectric constant κ in the CGSs system are identical;
both of them are dimensionless numbers.
Option A is correct, as Reason is explanation for Assertion
