Statement I: The electrical conductivity of a metal decreases as temperature increases.

Statement II: This impedes the flow of electrons, when an electric field is applied.

View answer and explanation

Correct option: B

Both Statement I and Statement II are correct but Statement II is not the correct explanation of Statement I

Option B (Both Statement I and Statement II are correct but Statement II is not the correct explanation of Statement I) is correct because both statements are true, but the impeding of electron flow is a general property, not the direct cause of decreased conductivity with increased temperature.
