Which term best describes liquid behavior under pressure?

The correct answer is incompressible. Liquids or fluids that behave under pressure are called incompressible fluids because they tend to behave through flowing movements. An example of an incompressible fluid is the lava which comes out of a volcano where once out of the atmosphere becomes dense and flows at a constant volume and velocity.

The most plausible answer is b, duration. the given amount of time is considered how long it last for.
