Why NF_3 cannot be hydrolysed, while NCl_3 can be readily hydrolysed?

Why is SiCl_(4) readily hydrolysed but C Cl_(4) is resistant to hydrolysis?

C Cl_(4) does not show hydrolysis but SiCl_(4) is readily hydrolysed because:

The reactivities of C Cl_(4) and SiCl_(4) are different. For example SiCl_(4) can be easily hydrolysed and is prone to substitution reactions, whereas C Cl_(4) is inert. The observed difference is because (a)carbon atom has smaller size than hence substitution is not possible (b)carbon is more electronegative than silicon ( c)silicon has low lying unoccupied orbitals (d) C-Cl bond is stronger than Si-Cl bond
