What are the three primary inspection methods listed?

• A. Ultrasonic Testing
• B. Visual, Physical, Advanced
• C. Visual, Physical, Ultrasonic
• D. Physical, Advanced, Thermal

Answer: (B)

The question tests understanding of the three broad inspection method categories used in this course: Visual, Physical, and Advanced. Visual inspection is the basic surface check—what you can see from access points, looking for obvious defects or deterioration. Physical inspection goes beyond sight, involving hands-on assessment, measurements, and checks of function, tolerances, and movement. Advanced inspection covers the range of nondestructive evaluation techniques used for deeper or hidden issues, such as ultrasonic testing, radiography, magnetic particle, dye penetrant, and infrared methods.

This is why the correct choice is the one that lists Visual, Physical, and Advanced together—the three primary categories as defined in the material. Other options are less accurate because they pick out a single technique (like Ultrasonic Testing) or mix a technique with categories (Visual, Physical, Ultrasonic) or treat a specific method (Thermal) as its own primary category.
