$ \chi_{1} $ and $ \chi_{2} $ are the magnetic susceptibilities of a paramagnetic material at temperatures $ T_{1} \ K $ and $ T_{2} \ K $ respectively. Then:

• A
  $ \chi_{1} = \chi_{2} $
• B
  $ \chi_{1} T_{1} = \chi_{2} T_{2} $
• C
  $ \chi_{1} T_{2} = \chi_{2} T_{1} $
• D
  $ \chi_{1} \sqrt{T_{1}} = \chi_{2} \sqrt{T_{2}} $
