Which of the following statements is correct about ferromagnetic materials?

Which of the following statements is correct about anti-ferromagnetic materials?

Given below are two statements regarding a ferromagnetic material: Assertion (A): The individual atoms in a ferromagnetic material possess a magnetic dipole moment and interact with one another in such a way that they spontaneously align themselves forming domains. Reason (R): At high enough temperature, the domain structure of a ferromagnetic material disintegrates. Thus, magnetization will disappear at a high enough temperature known as the Curie temperature. In the light of the above statements, choose the correct answer from the options given below:
