Concept:The diagram shows a farm sprayer, and the labelled part I is the nozzle.
Explanation:The nozzle is fitted at the end of the sprayer lance or boom.
Its main function is to break the liquid chemical or water into fine droplets.
This process is called atomisation.
It helps in the uniform distribution of sprays over crop surfaces.
The nozzle does not store the liquid inside the tank.
It does not control the pressure of the sprayer system.
It also does not prevent leakages from the sprayer.
Therefore, the role of part I is specifically to reduce water or spray liquid to fine droplets.
Answer:D. reducing water to droplets
