Best answer
Right answer is (d) Pressure test

Best explanation: Pressure test is basically a type of non-destructive test in which a gas is injected in a closed casting, and then the casting is dipped into water and if it produces any leak of gas in the water, that basically shows presence of defects in the casting that can be simply observed by visual inspection. And the test like a stress test, hardness test and crash test, these are related to the destructive testing of materials.
