The Correct Option is A
Solution and Explanation
Spark plug cleaners work on the principle of blasting an abrasive material to clean carbon deposits.
The wing type Air Valve Control regulates the flow of both air and sand inside the cleaner.
Compressed air carries the sand particles and directs them onto the spark plug electrodes.
Controlling both air and sand ensures efficient cleaning without damaging the spark plug.
If only air or only sand is controlled, cleaning efficiency drops.
Pressure is just the force behind the flow; the actual materials flowing are air and sand.
Therefore, the right answer is air and sand.
