Final answer:
The most helpful question for determining the purpose and audience of your own writing is 'For whom am I writing, and why am I writing this?'
Therefore, option D is correct.
Step-by-step explanation:
When determining the purpose and audience for your own writing, the question that would be most helpful is option D: 'For whom am I writing, and why am I writing this?'
This question encourages you to consider your target audience and their needs, as well as the purpose of your writing. Understanding your audience allows you to tailor your message to effectively communicate with them, while knowing your purpose helps you stay focused and ensure that your writing meets its intended goals.
For example, if you are writing an argumentative essay about the importance of recycling, your audience may be policymakers or environmentally conscious individuals. Knowing this audience and their values will help you shape your writing to resonate with them. Similarly, identifying your purpose as influencing readers to adopt recycling practices will guide your writing and help you craft a compelling argument.
