Answer:

B

Explanation:

Gases slightly dissolve in water and are held loosely by weak inter-molecular forces. When the water gains temperatures, the kinetic energy of the water molecules including those of the gases increase. The dissolved gas molecules are therefore able to overcome the weak forces of attraction in the water and escape through the surface.
