Answer:
A. Yield strength
Explanation:
Yield stress is defined as the stress in psi at which a fastener assumes a specified limited permanent set.
Because yield strength of any component is the maximum strength of the component up to which it remains elastic. At yield point, the materials starts to yield. That means the component goes into the plastic range after it crosses yield point and is permanently set,it cannot regain its original dimensions.
Therefore, A). Yield strength is the answer.
