Right answer is (d) Jetting

The best I can explain: Development of well by high velocity jetting is one of the most effective methods. In this method, the fine particles are washed out of the aquifer due to the shooting of high-velocity water stream through the screen openings. These fines get back into the well due to the turbulence created by the jet. The entire surface of the screen can be covered by gradual raising, lowering and slowly rotating the jetting tool.
