The correct answer identifies that data-management tasks are triggered by actions that include record creation, updates, and deletion. In Dynamics 365, these actions encompass the full spectrum of how data is manipulated within the system.
When users interact with sales opportunities, it's essential for the platform to track not just when a new record is created or when an existing record is updated, but also when records are deleted. Each of these actions can have significant implications for data management tasks, such as maintaining data integrity, ensuring compliance, and enabling data audits.
Field modifications, although crucial, are generally seen as part of updates rather than standalone triggers for data-management tasks. User notifications, while important for user experience, do not inherently instigate data management functions in the context of interaction with sales opportunities. Consequently, the comprehensive nature of the answer reflects the broader array of interactions that necessitate data management in Dynamics 365.
