Which operation may require rebalancing in an AVL tree?

Step 1: Understand what an AVL tree is. An AVL tree is a type of binary search tree that maintains balance to ensure efficient operations.
Step 2: Know that an AVL tree is balanced if the heights of the two child subtrees of any node differ by no more than one.
Step 3: Learn that when you insert a new node into an AVL tree, it can change the heights of the nodes and potentially make the tree unbalanced.
Step 4: Identify that if the tree becomes unbalanced after an insertion, it needs to be rebalanced to restore the AVL property.
Step 5: Recognize that rebalancing can be done using rotations (single or double) to adjust the structure of the tree.
