In a routing plan, BU stands for which of the following?

• A. Business Unit
• B. Build Up
• C. Break Up
• D. Begin Update

Answer: (B)

Routing plan acronyms map to specific actions in how a route is constructed. In this context, BU is used to denote the action of assembling or layering the route step by step, i.e., a Build Up of the route. This framing fits the idea of progressively adding components or steps to create the complete path.

While BU can also stand for Business Unit in other contexts, that interpretation doesn’t describe an operation within routing planning. Break Up would imply splitting the route, which isn’t the standard action here. Begin Update sounds like starting an update process, not a defined routing-step label. Therefore, Build Up best captures the intended meaning in a routing plan.
