PLEASE HELP!

Sebastian has two beakers. The first beaker has 100 mL of water and a second beaker has 500 mL of water. In order to identity common physical properties between both substances, he heats both substances to 100°C Sebastian notices that both
substances begin to bubble What physical property does this experiment provide evidence for?

A: This experiment provides evidence of a change in the volume of the samples

B: This experiment provides evidence that the volume remains constant in the samples.

C: This experiment provides evidence that the boling point does change based on sample size

D: This experiment provides evidence that the boiling point is a property independent of the amount of water
