Final answer:
Online prompting is a control plan used to request user input by displaying prompts or questions. This interactive method ensures accurate data entry and assists users in system navigation.
Step-by-step explanation:
The control plan that requests user input or asks questions that the user must answer is known as online prompting. This approach is used to guide users through a process by displaying prompts or questions that they need to respond to, often in the form of an interactive session. This helps in ensuring that the necessary data is input correctly and also assists users in navigating through complex systems or forms.
In contrast, document design refers to the visual layout and structure of printed or electronic documents. Written approval is a formal acknowledgment or authorization that something meets certain requirements, and preformatted screens are templates with predefined layouts and fields that aid in standardizing data entry but do not necessarily prompt users for input.
