Answer
Brief Explanations:
Boiling - point is related to intermolecular forces. $F_2$ is a non - polar molecule with only weak London dispersion forces. $H_2O_2$ has hydrogen bonding, $CF_2H_2$ has dipole - dipole forces, $NBr_3$ has dipole - dipole forces and $H_2S$ has dipole - dipole forces. Hydrogen bonding and dipole - dipole forces are stronger than London dispersion forces for small molecules. So, the substance with the weakest intermolecular forces will have the lowest boiling point.

F₂
