The correct answer is:

(a) True

Explanation: In ultrasonic inspection, signal processing techniques are indeed used to accurately detect and assess porosity in castings. By analyzing the returned ultrasonic waves (which are reflected by internal structures such as voids or porosity), the technique can identify inconsistencies in the material, including the presence of porosity. Advanced signal processing algorithms help in improving the accuracy and reliability of these indications, making ultrasonic inspection a valuable non-destructive testing method in casting quality control.
