Material included in a list published by an organization acceptable to the AHJ is described as:

• A. Certified
• B. Listed
• C. Approved
• D. Labelled

Answer: (B)

The main idea is about formal evaluation and acceptance by a recognized testing body. When a material is included in a list published by an organization acceptable to the AHJ, it has been tested or evaluated to meet specific safety or performance standards, and that organization has published it as a listed item. This listing is what the AHJ uses to verify conformity for installations, so the material is considered approved for use in the intended application.

Why this fits best: listing ties the item to an independent evaluation and a public reference (the list) from a recognized authority. Other terms differ in emphasis: certification is typically a manufacturer’s claim; an item being approved isn’t tied to a published, recognized list; labeling merely indicates compliance on the item's surface but doesn’t guarantee it appears on a formal listing. Listing directly communicates that the product belongs to a vetted set of approved items documented by a reputable body.
