What best differentiates base direction from wrap pattern?

• A. Base direction describes how the wrap is positioned relative to the base area (on-base, half-off-base, off-base); wrap pattern refers to the geometry of sectioning used to create curl texture.
• B. Base direction and wrap pattern are the same concept.
• C. Base direction describes the geometry of the sectioning, while wrap pattern describes the wrap relative to the base.
• D. Base direction is about the chemical; wrap pattern is about the rod.

Answer: (B)

The idea being tested is whether base direction and wrap pattern are separate ideas or the same. In this context, they describe the same directional approach when wrapping the hair around the rod: how the hair moves from the base as it is wrapped and how that wrap directs curl formation. Because both terms reference the path and orientation of the wrap relative to the base, they’re effectively interchangeable descriptors of the same concept. The other phrasing would imply a distinction or a different element (like separate geometry or a chemical aspect), but that isn’t how these terms are viewed here.
