• A. Five
• B. Seven
• C. Nine
• D. Eleven

Answer: (C)

Sprayers have a set of essential parts that work together to store, pressurize, filter, and deliver the spray. In the standard breakdown used for pesticide practice, nine major components are identified as part of a sprayer. Think of the tank as the storage for the chemical, and the pump as what moves that liquid through the system. A pressure-regulating device and gauge set the working pressure and show you what it is. Agitation keeps powders or driftable mixtures evenly mixed so they don’t settle. A filter or screens protect the nozzles from clogging. Hoses, fittings, and valves carry and control the liquid flow from tank to pump to nozzle. The nozzle itself determines the spray pattern and droplet size, while the boom or wand directs the spray to the target area. Finally, the operation controls—such as shut-off or bypass valves—allow you to start, stop, or relieve pressure safely. Missing any one of these parts would leave the sprayer unable to perform properly, which is why nine is the correct count in this context.
