Best answer
The correct option is (b) False

Best explanation: Visual inspection of each casting ensures that none of its features has been omitted or malformed by moulding errors, shut running, or mistakes in cleaning. Most of the surface defect can be observed easily at this stage, but for sensitive testing, other expensive methods of NDT are implemented.
