The correct answer is:
$X \lt Z \lt Y$
$\begin{aligned} \mathrm{X}=[\mathrm{Ti} & \left.\left(\mathrm{H}_2 \mathrm{O}\right)_6\right]^{4+}, \mathrm{E} \cdot \mathrm{C} \text { of } \mathrm{Ti}^{4+}=3 d^{\circ} \\ n & =0 \\ \mu_B & =0 \\ Y & =\left[\mathrm{Mn}\left(\mathrm{H}_2 \mathrm{O}\right)_6\right]^{2+}, \mathrm{E} \cdot \mathrm{C} \text { of } \mathrm{Mn}^{+2}=3 d^5 \\ n & =3 \\ \mu_B & =3.87 \mathrm{BM} \\ \mathrm{Z} & =\left[\mathrm{Cr}\left(\mathrm{H}_2 \mathrm{O}\right)_6\right]^{3+}, \mathrm{E} \cdot \mathrm{C} \text { of } \mathrm{Cr}^{3+}=3 d^3 \\ n & =3 \\ \mu_B & =3.87 \mathrm{BM}\end{aligned}$
Hence, the correct order of magnetic moment of $X, Y, Z$ is
$X \lt Z \lt Y$
Hence, the correct order of magnetic moment of $X, Y, Z$ is
$X \lt Z \lt Y$
