Quiz: Binary Search Trees

When deleting a node with two children from a BST, why do we use the inorder successor (smallest in right subtree)?

1. A.It minimizes the tree height after deletion
2. B.It's always a leaf node, making deletion simpler
3. C.It's larger than all left descendants and smaller than all other right descendants, maintaining BST property
4. D.It's the closest value to the deleted node
