Which of the following braiding styles is specifically mentioned as free-hanging?

Individual braids are specifically recognized as a free-hanging style because they are created by sectioning the hair into separate strands and braiding each strand individually. This technique allows the braids to hang loosely and independently from the scalp, without being tightly attached. Individual braids can vary in thickness and length, offering versatility in styling and are often used for various extensions and protective styles.

In contrast, other styles like inverted braids, twists, and locks involve different techniques or structures, which may result in a more attached or constrained style where the braids do not hang freely. Individual braids effectively allow for movement and flexibility, which is a defining characteristic of free-hanging styles.
