Consider the pseudo code: int avl(binarysearchtree root): if(not root) return 0 left_tree_height = avl(left_of_root) if(left_tree_height== -1) return left_tree_height right_tree_height= avl(right_of_root) if(right_tree_height==-1) return right_tree_height Does the above code can check if a binary search tree is an AVL tree?

Answer: Option A
