The Correct Option is A
Solution and Explanation
Cavitation occurs when local pressure drops below vapor pressure of liquid, causing vapor bubbles.
These bubbles collapse at higher pressure regions, damaging pump components.
These bubbles collapse at higher pressure regions, damaging pump components.
