A comparative study of $E^{\circ }\left({\mathrm{M}}^{3+}\mid {\mathrm{M}}^{2+}\right)$ values show varying trends. Choose the correct trends (along with po88ible reason) among the following

A low number for Sc indicates that ${\mathrm{Sc}}^{3+}$, which has a noble gas structure, is stable. A low value for Sc indicates that ${\mathrm{Sc}}^{3+}$s stable and has a noble gas structure. Due to the '${\mathrm{d}}^{10}$' configuration's stability, Zn has the greatest value.

Due to the ${\mathrm{d}}^{10}$configuration's stability, Zn has the greatest value. The increased stability of ${\mathrm{Mn}}^{2+}$${\mathrm{d}}^5$ and ${\mathrm{Fe}}^{3+}$${\mathrm{d}}^5$ is demonstrated by the comparably high value for Mn and low value for Fe. Due to the stability of the partially filled orbital.

The relatively high value for Mn indicates that ${\mathrm{Mn}}^2$) is very stable, whereas the relatively low value for Fe indicates that Demonstrates${\mathrm{Fe}}^{3+}$ has additional stability's relatively low value and the stability of ${\mathrm{V}}^{2+}$ are connected.

 In relation to the stability over the half-filled level, Unit 9, the relatively low figure for V is significant. demonstrates the 3D series of transition metal halides' stable halides. Hence, Comparatively low value for V is related to the stability of half filled $t_{2g}$ in $V^{2+}$
