(B) $Ti$ $\rightarrow [Ar] 3d^{2} 4s^{2}, Ti^{3+}$ $\rightarrow [Ar] 3d^{1} 4s^{0}$ ($1$ unpaired electron)$Cr$ $\rightarrow [Ar] 3d^{5} 4s^{1}, Cr^{3+}$ $\rightarrow [Ar] 3d^{3} 4s^{0}$ ($3$ unpaired electrons)$Co$ $\rightarrow [Ar] 3d^{7} 4s^{2}, Co^{3+}$ $\rightarrow [Ar] 3d^{6} 4s^{0}$ ($0$ unpaired electrons because $NH_3$ is a strong field ligand causing pairing)$Zn$ $\rightarrow [Ar] 3d^{10} 4s^{2}, Zn^{2+}$ $\rightarrow [Ar] 3d^{10}$ ($0$ unpaired electrons)Since $[Cr(NH_3)_6]^{3+}$ has the highest number of unpaired electrons $(3)$,it exhibits the highest paramagnetic behaviour.

Which of the following complex compounds will exhibit highest paramagnetic behaviour?
