  1. Plough

  2. Beam

  3. Hoe

  4. Seed drill
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

  • Cultivators can be used instead of the hoe. Cultivators are used to stir and pulverize the soil, either before planting (to aerate the soil and prepare a smooth, loose seedbed) or after the crop has begun growing to kill weeds. Unlike a harrow, which disturbs the entire surface of the soil, cultivators are designed to disturb the soil in careful patterns, sparing the crop plants but disrupting the weeds. 

Therefore, the correct answer is option C.
