If the Assertion is correct but Reason is incorrect.

(C) $NF_3$ is a weaker ligand than $N(CH_3)_3$ because fluorine is highly electronegative,which withdraws electron density from the nitrogen atom,making the lone pair less available for donation.In contrast,$N(CH_3)_3$ is a stronger ligand because the methyl groups are electron-releasing,increasing the electron density on the nitrogen atom.$NF_3$ does not ionize to give $F^{-}$ ions in aqueous solution; it is a covalent molecule.Therefore,the Assertion is correct,but the Reason is incorrect.
