According to Curie-Weiss law

Correct option is A

​$$\text{Curie–Weiss Law is a modified form of \textbf{Curie’s Law} for \textbf{ferromagnetic materials} above the Curie temperature.} \\\text{It states:} \\\chi = \frac{C}{T - \theta}\\[10pt]\textbf{Where:} \\\bullet \chi = \text{Magnetic susceptibility} \\\bullet C = \text{Curie constant} \\\bullet T = \text{Absolute temperature} \\\bullet \theta = \text{Weiss constant (accounts for internal molecular field)}\\[10pt]\text{This law indicates that susceptibility decreases with increasing temperature but includes a correction due to molecular interaction.}$$​​
