Line 3 and 4 with the label Cd stand for?

• A. Conductive properties
• B. Cold resistance
• C. Chemical resistance
• D. Calibrated diameter

Answer: (A)

The main idea here is how property codes on test lines indicate what aspect of the material is being described. When you see the label Cd on a line, it points to conductive properties—the material’s ability to conduct electricity. That makes sense in an audit context where electrical characteristics matter and separate codes are used for different attributes. So the best match is conductive properties, because Cd is used to flag electrical conductivity-related information. The other options refer to different kinds of attributes (cold resistance, chemical resistance, or a physical dimension like diameter), which would be labeled with other codes rather than Cd.
