You are a defect analyst, the fracture surface appears relatively smooth to the eye, but under electron microscopy you have noticed that there are a series of microscopic bands that spread out from a defect in the surface. Which statement is correct about the likely failure mechanism of the component?

I need explanation and correct answer pls
You are a defect analyst, the fracture surface appears relatively smooth to the eye, but under electron microscopy you have noticed that there are a series of microscopic bands that spread out from a defect in the surface. Which statement is correct about the likely failure mechanism of the component? a. It failed as a result of cyclic loading b. It failed via brittle fracture due to the defect in the surface being above the critical flaw size c. It failed due to the service temperature being below the Brittle to Ductile Transition Temperature (BDTT) d. It failed due to stress corrosion cracking
