Correct option is (b) False

Easy explanation: Destructive type of testing suffer from the disadvantage that the saw cuts may miss the flaw or the sample may not represent the behavior of the entire lot, and as the name shows that it damages the product while testing of the castings. So, non-destructive tests are generally more commonly relied upon than destructive tests.
