Which of the following is true

Explanation

Paramagnetism is temperature-dependent, which is explained by Curie's law. This law states that the magnetic susceptibility of a paramagnetic material is inversely proportional to its temperature. As the temperature increases, the thermal energy causes more randomisation in the alignment of magnetic dipoles, resulting in a decrease in magnetic susceptibility. Option A is incorrect because diamagnetism is a quantum mechanical effect that is generally independent of temperature. It arises from the orbital motion of electrons, creating tiny magnetic fields. Option C is incorrect because it incorrectly states that paramagnetism is temperature independent, which contradicts Curie's law. Option D is incorrect because there is a true statement among the options provided, specifically about paramagnetism being temperature-dependent.
