Best answer
Correct choice is (b) get a velocity field that satisfies the continuity equation

The best explanation: The first corrector step of the PISO algorithm results in a velocity field which will satisfy the continuity equation. The equations resulting from this step is the same as the equations used in the SIMPLE algorithm.
