The Product Increment is defined as the sum of all product backlog items that have been completed up to the end of the current sprint, which includes all completed items from previous sprints as well. This means that every increment builds on the last, cumulatively adding to the total functionality of the product.

The other options focus on different timeframes or concepts that do not align with the definition of the Product Increment. For instance, option A mentions only the current sprint's completed backlog items, which does not account for the work completed in past sprints. Option C refers to items planned for future sprints, which have not yet been developed and therefore cannot contribute to the current increment. Lastly, option D addresses the achievement of sprint goals, rather than the tangible functionality achieved in the form of completed backlog items, which is critical to understanding the Product Increment.

The correct understanding of the Product Increment emphasizes its cumulative nature, representing all completed work across all sprints leading up to the current point.
