Match each statement with its description: try finally Choose... public void print() \{ System.out.print ln (payload); if (left != null) \{ left.print(); \} if (right != null) \{ right.print(); \} Select the correct statement about it: Select one: a. If both the left and the right sub-trees are null, it only prints the payload of the current node b. The base case checks whether the current node is null c. If the left sub-tree is null, then the right subtree is not printed
