Effective business writing should communicate clearly, professionally, and efficiently without distracting the reader. A memorandum should focus attention on the message, evidence, recommendation, or decision required—not on the writer’s style. Therefore, drawing positive attention to the writing style is not a proper objective. The style should be appropriate, direct, respectful, and suited to the delivery method and audience. Treating receivers with respect supports professional communication and reduces resistance. Matching presentation and delivery helps ensure the message is received correctly. Developing ideas without overstatement supports accuracy, objectivity, and credibility. These principles are especially important in internal audit communications, where clarity and neutrality affect management acceptance and governance decisions. Therefore, Option A is the exception and the correct answer.
