A paramagnetic substance is placed in external magnetic field \( B \) and absolute temperature \( \mathrm{T} \). When external magnetic field, is tripled and temperature is quadrupled then percentage change in magnetization is
(a) \( \frac{3}{4} \% \)
(b) \( \frac{4}{3} \% \)
(c) \( 25 \% \)
(d) \( 75 \% \)
