D Correct answer
Explanation

The OSI model layers from highest (7) to lowest (1) are: Application (7), Presentation (6), Session (5), Transport (4), Network (3), Data Link (2), Physical (1). Layer 7 (Application) is closest to the user experience, while Layer 1 (Physical) deals with actual bit transmission over the medium. Memorizing 'All People Seem To Need Data Processing' helps recall the order from top to bottom.
