The correct elevation that the hair is held in a triangular graduation haircut is b) 45 degrees.
Triangular graduation is a technique used in hair cutting that creates layers in the hair, with shorter layers underneath and longer layers on top. The elevation, or angle at which the hair is held, affects the length of the layers and the overall shape of the haircut.
A 45-degree elevation is commonly used for triangular graduation because it creates a smooth transition between the shorter and longer layers. Holding the hair at this angle allows the hair to be cut in a way that creates fullness and movement.
