Final answer:
Claw clips are the ideal choice for separating the hair into large sections because of their ability to hold a thick bundle of hair securely compared to other types of clips.
Step-by-step explanation:
When separating the hair into large sections, the most effective type of clips used are claw clips. These clips have a wide opening and interlocking teeth that can hold a thick bundle of hair securely without slipping. Unlike duckbill clips, which are better for smaller sections or detailed styling, claw clips can handle the weight and bulk of larger hair sections. Snap clips and bobby pins are also not typically used for this purpose because they do not offer the same level of hold as claw clips for large sections of hair.
