It is important to make small check dams across the flooded gullies because they

(i) hold water for irrigation

(ii) hold water and prevent soil erosion

(iii) recharge ground water

(iv) hold water permanently

(b)

It is important to make small check dams across the flooded gullies because they recharge groundwater.

These small dams assist in withholding water.  This gives dampness to the vegetation cover, subsequently preventing soil erosion.

Therefore statements (ii) and (iii) are correct.

Hence option (b) is correct.
