Best answer
The correct choice is (a) decoupling of pressure and velocities

The best explanation: The uncoupling between pressure and velocities cause a number of problems. Coupling can be enforced if the different flow variables are stored in the staggered grid form. Here, pressure and velocity are stored in different places.
