Final answer:
Arc base pin curls are commonly referred to as Ribbon curls.
So the correct answer is Option a) Ribbon
Step-by-step explanation:
Ribbon curls, characterized by an arc-shaped base, are a hairstyling technique where the hair is smoothly wrapped around the curling tool.
The resulting curls lie flat against the scalp, creating a ribbon-like appearance. This technique is often used to achieve a sleek and polished hairstyle, and the arc base ensures a controlled and uniform arrangement of the curls. The term "Ribbon" reflects the flat and neatly arranged nature of the curls, providing a classic and elegant look in hairstyling.
