Assertion :When dielectrics are placed in an electric field, practically no current flows in them because, unlike metals, they have no loosely bound, or free, electrons that may drift through the material. Instead, electric polarization occurs. Reason: Ideally there is some amount of undetectable current in insulator also.

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
Explanation:
When dielectrics are placed in an electric field,
practically no current flows in them because, unlike metals, they have no
loosely bound, or free, electrons that may drift through the material. Instead,
electric polarization occurs.
Ideally there is some amount of undetectable
current in insulator also. An electrical insulator is a material
in which the electron does not flow freely or the atom
of the insulator have tightly bound electrons whose internal electric
charges do not flow freely; very little electric current will flow
through it under the influence of an electric field.
Both are correct but reason is not explanation
for assertion.
Hence option B is correct
