B

MCQ. Bernoulli's principle shows that, at points in a moving fluid where potential energy change is very small

1. pressure is low where velocity is low and similarly, pressure is high where velocity is high
2. pressure is low where velocity is high and conversely, pressure is high where velocity is low
3. pressure becomes independent of velocity of moving fluid
4. pressure remain independent of speed of stationary fluid
