Correct answer: A. When similar guiding criteria apply in similar cases
Explanation: The direct answer is option A: policy increases consistency when similar guiding criteria are applied in similar cases. In business studies, a policy is a general decision guide. It tells managers the broad approach to follow when recurring or comparable situations arise. Step by step, the manager identifies the situation, checks the relevant policy, applies the same guiding principle and reaches a decision that is reasonably consistent with decisions in similar cases. Option A is correct because common criteria reduce arbitrary differences while still allowing some judgment. Option B is wrong because if every manager acts only according to personal wish, similar cases may receive different treatment. Option C is wrong because the absence of a criterion creates confusion and inconsistency, not uniformity. Option D is wrong because secrecy concerns information sharing, not the existence of a common decision guide. Policies do not make every decision identical, but they provide a stable direction. Memory cue: policy means a common guide for comparable decisions.
