Apples are Room 4. Talk to the "hologram" and choose the easy version. Now, the 4-apple basket (the one you can't move) must be surrounded by other baskets on all 4 sides. Similarly, each 3-apple basket must have 3 other baskets next to it. And every basket with 2 apples needs 2 adjacent baskets. Remember that "next to it" means left/right/up/down, i.e. diagonally placed baskets are irrelevant.
