In abrasive jet machining process, the main mechanism of material removal takes place due to?

Correct option is C

​$$\begin{aligned}&\textbf{Abrasive Jet Machining (AJM)} \text{ is a } \textbf{mechanical material removal process}. \\&\text{Here's how it works:} \\[0.5em]&\bullet\ \text{High-speed abrasive particles (e.g., SiC, Al}_2\text{O}_3\text{) are } \textbf{carried by a pressurized gas stream} \\&\quad \text{(e.g., air, CO}_2\text{).} \\[0.5em]&\bullet\ \text{These particles } \textbf{strike the work surface} \text{ at high velocities } (\sim 200 \text{–} 300\, \text{m/s}). \\[0.5em]&\bullet\ \text{The } \textbf{kinetic energy} \text{ of the particles is transferred to the surface, causing } \\&\quad \textbf{micro-fracture, chipping, and erosion}. \\[1em]&\text{This results in } \textbf{material removal due to mechanical impact}, \text{ effective on } \\&\textbf{brittle materials} \text{ like glass, ceramics, and hard plastics}.\end{aligned}$$​​
