The correct option is (a) Suction dredger

For explanation: In suction dredgers, the suction head is provided with jets or rotating blades so as to cut or loosen the bed material and the suction openings through which the soil and the water mixture enters into the suction pipe. It cannot operate on rocky or Boulder River reaches. These dredgers can make cuts of about 10 m width through sand bars in order to achieve wider cuts.
