While researching scuba diving, Pablo reads how hot a tank should get while being filled with air. Which law best explains why the scuba tank would heat up?

As air is forced into a scuba tank, the tank’s volume stays essentially constant while its pressure rises. Gay-Lussac’s law says that, at constant volume, pressure and temperature increase together, so the air and tank heat up. Thus the correct choice is Gay-Lussac’s law, because as the pressure increases, the temperature increases.
