The elements of VA group direcly combine...

The elements of VA group direcly combines with halogens and form trihalides of the type `MX_(3) (M-VA` group element, X- halogen). All the trihalides are stable except `NCl_(3),NBr_(3)` and `NI_(3)`.
The tendency of act as Lewis bases of these trihalides is in the order of

A

`NF_(3) gtNCI_(3) gt NBr_(3) gt NI_(3)`

B

`NCI_(3) gt NF_(3) gt NBr_(3) gt NI_(3)`

C

`NI_(3) gt NBr_(3) gt NCI_(3) gt NF_(3)`

D

`NBr_(3) gt NCI_(3) gt NI_(3) gt NF_(3)`
