D. Even though the temperature is the same, container B has more thermal energy, since it has more liquid than container A.
Explanation:
Whenever there is an increase in the volume of the pink liquid, it is due to the increase in temperature.
When the temperature increases, the molecules move farther apart as much as possible.
When the molecules moves apart from each other and collide with each other, so that its kinetic energy also increases, So thermal energy of the container B is more compared to the container A.
