What is wrong with the following function?void* _retrieve (AVL_TREE* tree, void* keyPtr, NODE* root){ if (tree->compare(keyPtr, root->dataPtr) < 0) return _retrieve(tree, keyPtr, root->left); else if (tree->compare(keyPtr, root->dataPtr) > 0) return _retrieve(tree, keyPtr, root->right); else return root->dataPtr; } // if root}
A. It is missing one recursive call to _retrieve. B. The first if should be "if (tree->compare(keyPtr, root->dataPtr) < 0)". C. The second if should be "if (tree->compare(keyPtr, root->dataPtr) >= 0)". D. It does not check if the data is not in the tree.
