OPTION C.
Step-by-step explanation:
Tech A and Tech B are both partially correct. Tech A is correct that compressed air can be used to clean dust off brakes. It is a commonly used method in the automotive industry. However, Tech B is also correct that some auto parts, including certain brake pads and linings, may contain asbestos.
Asbestos was commonly used in brake pads and linings in the past because of its heat resistance and durability. However, due to the health risks associated with asbestos exposure, its use in the automotive industry has significantly decreased and many manufacturers now use alternative materials.
It is important for technicians to take precautions when working with auto parts that may contain asbestos, such as wearing appropriate protective gear and following proper handling and disposal procedures.
