Correct choice is (a) True

The best I can explain: The basic principle in well development is to cause reversals of flow that will rearrange the aquifer particles through the screen openings. This breaks down the bridging of the groups of particles. When the flow is in one direction small particles bridge between large particles across the screen openings.
