Note that the replacement should be the least of the numbers equal to or greater than the deleted element. Which of the following about the resulting tree are true?(A) The node for 75 has only one child.(B) The node for 65 has a left child.(C) The node for 41 has two children.(D) The node for 65 is a child of the node for 94.
