Answer: (iii) Biocompatibility

For an implantable medical device, the material must be biocompatible, meaning it should not produce an unacceptable toxic, inflammatory, allergic, or other harmful biological response. Cost, hardness, and surface finish can matter, but biological safety is the primary requirement for an implanted device.
