JEE Main 2020 Physics question

A paramagnetic sample shows a net magnetization of 6 A/m when it is placed in an external magnetic field of 0.4 T at a temperature of 4 K. When the sample is placed in an external magnetic field of 0.3 T at a temperature of 24 K, then the magnetization will be

• (A)1 A/m
• (B)2.25 A/m
• (C)0.75 A/mCorrect
• (D)4 A/m
