Correct answer: C. Sintering
- A. Precipitation
- B. Fusion
- C. Sintering
- D. Agglomeration

Sintering is the controlled heating of compacted metal powder below its melting point, allowing particles to bond and gain strength. Fusion would melt the material, while agglomeration refers to forming larger clusters rather than strengthening a pressed compact.
