Best answer
Right answer is (b) Check dams

To explain I would say: A small sometimes temporary, dam constructed across a drainage ditch, swale, or channel to retain water upstream, so that the water percolates into the ground and recharges the groundwater table is a check dam. It is usually constructed to reduce the erosion of soil.
