* A. Berber: This is a texture style of carpet. Berber carpets are known for their tightly looped, nubby texture, often with a slightly rough feel. They are typically made from wool or nylon fibers and offer durability.
* B. Multi-level: This is a construction technique used to create texture in carpets. Multi-level carpets have different loop heights, creating a visual and tactile interest. This technique can be used to create various texture styles, including berber, cut pile, or even sculptured carpets.
* C. Loop-cut: This is a construction technique that combines looped and cut fibers to create a unique textured surface. This technique offers a variety of visual and tactile textures, often mimicking the look of natural materials like grass or woven fabrics.
* D. Loop: This is a basic construction technique. Loop carpets have all fibers in a looped form, creating a smooth and durable surface. While "loop" describes a construction technique, it's not a specific texture style like Berber.
Therefore, the answer to your question is A. Berber.
