The term 'arch' in hairstyling specifically refers to the shape created in the brow area when trimming hair. This is particularly relevant when styling bangs or managing the overall eyebrow area, as it provides a defined angle or contour that can enhance the wearer's facial features. The arch is essential for achieving a polished and intentional look, especially in styles where the brow line is accentuated.

When considering the other aspects of hairstyling, 'length' pertains to how long the hair is cut, 'volume' relates to the fullness and body of the hair, and 'color gradient' describes how color transitions are applied to hair. While these elements are important in the overall styling process, they do not capture the specific significance of the arch in relation to hair trimming and shaping around the brow area. Therefore, the association of the term 'arch' with the brow shape is what makes option B the correct choice.
