Given below are two statements: Statement-I: Since fluorine is more electronegative than nitrogen, the net dipole moment of $\mathrm{NF}_3$ is greater than $\mathrm{NH}_3$. Statement-II: In $\mathrm{NH}_3$, the orbital dipole due to lone pair and the dipole moment of NH bonds are in opposite direction, but in $\mathrm{NF}_3$ the orbital dipole due to lone pair and dipole moments of $\mathrm{N}-\mathrm{F}$ bonds are in same direction. In the light of the above statements. Choose the most appropriate from the options given below.
