Option: 1 \left ( b \right ),\left ( c \right )
Option: 2 \left ( b\right ),\left ( d \right )
Option: 3 \left ( a \right ),\left ( d \right )
Option: 4 \left ( a \right ),\left ( c \right )

For diamagnetic material, \chi \Rightarrow negative
The plot shown is (c) is correct for magnetic susceptibity (X) us temperature (T)
We know that
M=\chi H
\chi \Rightarrow negative
slope for M vs H graph is \chi
\therefore slope is negative for diamagnetic substance
The correct option is (4)
