Which outcome results when exceeding piston speed constraints in engines?

💡 Explanation

Cavitation erosion increases because inertial forces lead to rapid pressure drops, causing vapor bubbles to form and collapse violently—known as hydrodynamic cavitation—eroding the cylinder walls; therefore, A is correct rather than B, C, or D due to other operational factors.
