The attractive force between these two molecules has most likely been produced by
covalent bonds.
dipole-dipole interactions.
dipole-induced dipole interactions.
London dispersion forces.

Answer 1

Dipole–dipole interactions.

The colored regions show permanent partial positive and partial negative charges on the two molecules, so the molecules align and attract via their permanent dipoles (not by covalent bonds, induced dipoles, or only dispersion forces).
