χ1and χ2 are susceptibilities of a diamagnetic substance at temperatures T1K and T2K respectively, then,

The correct option is A χ1=χ2χ1 = χ2The magnetic susceptibility of diamagnetic substance is independent of the temperature.

$χ_{1}$ and $χ_{2}$ are susceptibilities of a diamagnetic substance at temperatures $T_{1} K$ and $T_{2} K$ respectively, then,

The correct option is A $χ_{1} = χ_{2}$
$χ_{1}$ $=$ $χ_{2}$
