Question
Assertion (A): Ferroelectric materials have spontaneous polarization.
Reason (R): Above curie temperature, ? = for ferro-electric materials.
Options
A. Both A and R are true and R is correct explanation of A
B. Both A and R are true but R is not correct explanation of A
C. A is true but R is false
D. A is false but R is true

Correct Answer

Both A and R are true but R is not correct explanation of A

Explanation

Both A and R are correct. Spontaneous polarization vanishes above ferroelectric curie temperature.
