Solution

The correct option is B Dipole-induced dipole interaction
$N H_{3}$ is a polar molecule whereas $C_{6} H_{6}$ is a non -polar molecule.
When the polar $N H_{3}$ molecule comes closer to the non -polar $C_{6} H_{6}$ molecule, it induces a dipole in the latter by disturbing the electron cloud.
Dipole-induced dipole is a weak attraction that arises when a polar molecule disturbs the electron cloud of a non-polar species.
