A student believes a business plan should never change once created. What is the correct response?

Correct answer: A plan may be revised based on new information and results

The direct answer is B: A plan may be revised based on new information and results. A business plan is a working guide, not an unchangeable promise. Step by step, an entrepreneur makes assumptions about customers, costs and methods; then tests the idea; receives feedback and observes results; compares evidence with the plan; and updates goals, methods or budgets when needed. Option B is correct because adaptation helps a venture respond to learning and market change. Option A is wrong because changing a plan is not always illegal; legal duties depend on the activity and applicable rules. Option C is wrong because a plan helps the entrepreneur manage the business as well as communicate with investors, lenders or partners. Option D is wrong because sensible change does not erase every goal; it can improve the route to those goals. Revising does not mean changing randomly: it means using evidence carefully. Memory cue: plan, test, learn, revise.
