Question 3 ( 1 Point What would the following private method do if considered to be within the Binary Tree class private int Unknown(Node-node) { if (node null) return if(node.left null && node.right null) if(node.left.data.equals (noderightdata) return 2p.data-Unknown(node.left) Unknown node.right: else return UnknowninodeJeft) + Unknown node.right else return Unknowninode.left) + Unknowntnode.right: } A) will return number of nodes which have two children. will return number of nodes for which a node has two children with the same data values. will return the overall summation of the data of the children of nodes that have two children with same data value and only one value of them is involved in the summation will return the overall summation of the data of the children of nodes that have two children with same data value. 1 Point Question 4 enthellewing BST after inserting and deleting 790, the order traversal we
