The question you should ask yourself to ensure that you address your audience correctly when writing a procedural document is: How much are my readers likely to know about my topic? (Option D)
Knowing the audience's prior knowledge about the topic is crucial in writing any procedural document because it helps you determine the appropriate level of detail, terminology, and tone to use. Writing a document that is too basic or too advanced for the audience can lead to confusion, frustration, or disengagement. By understanding the readers' knowledge level, you can ensure that the document meets their needs and provides the information they require in a way that is clear and easy to follow.
