Step-by-step explanation:
The opening d) "I know you are busy, but please answer the following request as soon as possible." is most likely to help create an effective direct-order message.
When writing a direct-order message, it is important to be clear, concise, and respectful of the recipient's time. The opening in option d) acknowledges the recipient's busy schedule, which can create a sense of empathy and understanding. This can help establish rapport and make the recipient more willing to respond promptly to the request.
Using an opening like "I know you are busy, but please answer the following request as soon as possible" puts the focus on the request and emphasizes the importance of a timely response. It is polite and straightforward, without being overly demanding or rude. This can increase the likelihood of the recipient taking the request seriously and responding promptly.
