I don't know very well about endurance but any property of material tensile strength good,elastic modulus and also stress but endurance is not exist in the property of material.

Understanding Material Properties
In mechanical engineering, materials are characterized by specific properties that define their behavior under various conditions. The options given represent different properties, but endurance limit stands out as not being an intrinsic material property.
Definition of Properties
- Ultimate Tensile Strength (UTS): This is the maximum stress a material can withstand while being stretched or pulled before breaking. It is a fundamental property of materials, indicating their strength.
- Elastic Modulus: Also known as Young's modulus, this measures a material's ability to deform elastically (i.e., non-permanently) when a force is applied. It is a critical property for understanding material stiffness.
- Yield Stress: This is the stress level at which a material begins to deform plastically. Beyond this point, the material will not return to its original shape, making it a crucial property for design and safety considerations.
Endurance Limit Explained
- Endurance Limit: This term refers to the maximum stress level a material can withstand for an infinite number of loading cycles without failing. Unlike the other properties, the endurance limit is not a fundamental characteristic of all materials but rather a property derived from fatigue testing.
- The endurance limit is particularly relevant for cyclic loading applications, such as in structural components subjected to repeated stresses. However, it varies widely among materials and is not applicable to all types of materials, notably non-ferrous metals.
Conclusion
In summary, while UTS, elastic modulus, and yield stress are intrinsic properties of materials, the endurance limit is conditional and varies based on the material's specific fatigue behavior. This distinction makes option 'A' the correct answer, as it is not universally applicable as a fundamental property of materials.
