Dipole-dipole interaction energy between stationary polar molecule propto (1/r3) and between rotating molecules propto (1/r6)

Q. Dipole-dipole interaction energy between stationary polar molecules is proportional to $x$ and that between rotating molecules is proportional to $y$ . Assume distance between polar molecules as $r$ , then $x$ and $y$ are

$\frac{1}{r ^{6}}, \frac{1}{r ^{3}}$

$\frac{1}{r ^{6}}, \frac{1}{r ^{6}}$

$\frac{1}{r ^{3}}, \frac{1}{r ^{3}}$

$\frac{1}{r ^{3}}, \frac{1}{r ^{6}}$

Dipole-dipole interaction energy between stationary polar molecule $\propto \frac{1}{r ^{3}}$ and between rotating molecules $\propto \frac{1}{r ^{6}}$
