Different kinds of polymers 1: In the list, which item is Acrylic 1?

• A. Acrylic 1
• B. Nylon 2
• C. Wood 3
• D. Natural nail plate 4

Answer: (A)

Identifying this item tests recognizing the term that matches a type of polymer used in nail enhancements. Acrylic refers to a synthetic polymer created for nail construction, forming a hard film when combined with monomer liquid and polymer powder. In the list, the item that literally names itself as Acrylic is the correct match, because it directly identifies the acrylic polymer. The other items represent different materials or natural tissue: Nylon would be a different polymer used in other nail components, Wood isn’t used as a nail polymer, and the Natural nail plate is the actual natural nail, not a polymer used in enhancements.
