Best answer
Right answer is (a) Jominy end-quench

To explain: Hardenability is the measure of inclination of a material to achieve hardness. It is affected by the alloying elements in the material and grain sizes. The hardenability of the material can be measured using the Jominy end-quench test method. Charpy and Izod impact testing methods, whereas Rockwell is a hardness testing scale.
