HDPE is strong and stiff and used for pipes and buckets. Which term describes this material?

Explanation:
Density in polyethylene determines how closely its polymer chains are packed, which in turn affects stiffness and strength. HDPE has a higher density due to less branching and more orderly packing, giving it the rigidity and durability needed for pipes and buckets. That specific term describes the material: High-Density Polyethylene. The other options refer to different polymers or to polyethylene in a non-specific sense, so they don’t capture the particular high-density, stiff nature of this material.
