Multiple Choice

AC stands for which material?

Explanation:
Understanding utility material abbreviations helps you interpret what a marked line represents. AC identifies asbestos cement, a material that combines cement with asbestos fibers and was commonly used for pipes and conduits in the past. It’s the only option among the choices that aligns with the AC abbreviation, whereas aluminum cement, air cooled, and arch wire refer to different things and are not standard meanings for AC in this context. Because AC can contain asbestos, treat it as potentially hazardous and follow proper safety and regulatory procedures before any disturbance.
