Does this look correct? If not, can you please explain?

Which of the following are reasons why the red-black tree is considered more efficient than the AVL tree? (Select all that apply.) Red-black trees are typically implemented using recursion rather than iteration. Although the code required to implement a red-black tree is generally considered to be more complex and harder to write than the code required to implement an AVL tree, it is nevertheless more efficient. Red-black trees only require a single, top-down pass to both add/remove an item and fix any imbalances that occur. Red-black trees are typically implemented using iteration rather than recursion. The code required to implement a red-black tree is generally considered to be less complex and easier to write than the code required to implement an AVL tree. Although red-black trees still require two passes to add/remove an item and fix any imbalances that occur, these passes can be executed in fewer steps than the corresponding operations in an AVL tree
