<prompt> Property of the material, which describes the resistance to abrasion is:HardnessYield strengthModulus of elasticityNone of the above  <response>: HARDNESSExcept for comparing one material with another, this term is difficult to define. In mineralogy, the relative hardness of a substance is based on its ability to resist scratching. In metallurgy and most other disciplines, the concept that is most generally accepted is that of resistance to indentation. It is on the basis of this process that most modern hardness tests are designed.Reference: PHILLIPS SCIENCE OF DENTAL MATERIALS, 12th ed page no 63
