A. For $[Ni(en{)}_3{]}^{2+}$ (octahedral, strong field) and $[Ni{F}_6{]}^{4-}$ (octahedral, weak field), the Crystal Field Stabilization Energy (CFSE) for $d^8$ configuration is higher for strong field ligands. Thus, CFSE of $[Ni(en{)}_3{]}^{2+}$ > CFSE of $[Ni{F}_6{]}^{4-}$. This option is correctly matched.
