Answer 1

The correct answer is:

(a) True

Explanation: In ultrasonic inspection, the method is highly accurate and sensitive to defects like cracks, voids, or inclusions within materials. However, when properly calibrated and applied, ultrasonic testing has a very low chance of rejecting good material. The test is non-destructive, meaning it does not alter the material being tested, and false positives (rejecting good material) are rare when proper procedures and standards are followed
