Solution
The correct option is D Seed drill
Weeding is the process of removal of unwanted plants(weeds) that grow along with the crops. Removal of weed is necessary as they compete with the main crops for nutrients, sunlight and water.
It should be done in an early crop stage. It can be done manually, using tools like khurpi, or can be done using seed drills. Weedicides like 2,4-D can also be used. But their use should be restricted as they are synthetic and are poisonous. They can adversely affect the health of the farmers.
