According to Hooke’s law, within the elastic limit stress/strain = constant. This constant depends on the type of strain or the type of force acting. Tensile stress might result in compressional or elongative strain; however, a tangential stess can only cause a shearing strain. After crossing the elastic limit, the material undergoes elongation and beyond a stage beaks. All modulus of elastically are basically constants for the materials under stress.
Just on crossing the yield region, the material will have
  1. reduced stress
  2. increased stress
  3. breaking stress
  4. constant stress

Answer

(A) reduced stress
