Answer: 3. Bernoulli's principle

A venturi-meter measures the flow speed of a liquid in a pipe. In the narrow part the speed is higher and the pressure is lower, and the pressure difference gives the flow rate. This follows Bernoulli's principle.

The other options are about moment of inertia and wave optics.
