The electronegaivity difference between ...

The electronegaivity difference between `N` and `F` is greater than that between ` N` and `H` yet the dipole moment of `NH_2` ( 1 .5 D) is larger than that of ` NF_3 ( 0. 2 D)`. This is because :

A

In `NH_3` as well as `NF_3` the atomic dipole and bond dipole are in opposite directions

B

In `NH_3` the atomic dipole and bond dipole are in the opposite directions whereas in `NF_3` these are in the same direction

C

In `NH_3` as well as in `NF_3` the atomic dipole and bond dipole are in the same direction

D

In `NH_3` the atomic dipole and bond dipole are in the same direction whereas in `NF_3` these are in opposite directions
