Given below are two statements: one is labelled as Assertion $(A)$ and the other is labelled as Reason $(R)$. Consider 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:

• A
  $(A)$ is true but $(R)$ is false
• B
  Both true, but $(R)$ is $NOT$ the correct explanation
• C
  Both true, and $(R)$ is the correct explanation
• D
  $(A)$ is false but $(R)$ is true
