Tag each sentence by its function first. B introduces the behaviour (conformity). A states a consequence of that behaviour (the dilemma of sameness). D states a response to the consequence (balance cohesion and expression). C gives a justification for why the response matters (creativity needs diversity).
A passage naturally reads introduction, then consequence, then response, then justification — so slot the tags in that order: introduction (B), consequence (A), response (D), justification (C). No sentence needs to be moved to make the logic hold, confirming the order is internally consistent.
\[ \boxed{B, A, D, C} \]
