 Ferromagnetism is considered an extreme form of paramagnetism. This is a true statement.

$\mathrm{Cr}^{2+}$ and $\mathrm{Nd}^{3+}$ have same unpaired electrons.
- $\mathrm{Cr}^{2+}:[\mathrm{Ar}] 3 \mathrm{~d}^4 \rightarrow 4$ unpaired electrons
- $\mathrm{Nd}^{3+}:[\mathrm{Xe}] 4 \mathrm{f}^3 \rightarrow 3$ unpaired electrons 

So they do not have the same number of unpaired electrons . 

Hence, the correct answer is option (4).
