How to answer the following question screenshot shows our binary search tree For the binary search trees, the public method, size, calls the private recursive method, recSize, and passes it a reference to the root of the tree, returning to the caller whatever is returned to it by recSize. Critique the following implementation of recSize assuming its parameter variable is node: if (node == null) return 0; else if ((node.getLeft() == null) && (node.getRight() == null)) return 1; else if ((node.getLeft() == null)) return (1 + recSize(node.getRight())); else return (1 + recSize(node.getLeft())); A. The code will throw a "null pointer exception" under certain circumstances. B. The code will return an incorrect result under certain circumstances. C. The code works correctly but could be simpler. D. The code works correctly. If an application uses the remove method on an Iterator object returned by our binary search tree: A. a TreeUnderflowException is thrown. B. an UnsupportedOperationException is thrown. C. the application will terminate. D. the most recently visited node of the tree will be r

For the binary search trees, the public method, size, calls the private recursive method, recSize, and passes it a reference to the root of the tree, returning to the caller whatever is returned to it by recSize. Critique the following implementation of recSize assuming its parameter variable is node:
if (node == null)
return 0;
else
if ((node.getLeft() == null) && (node.getRight() == null))
return 1;
else
if ((node.getLeft() == null))
return (1 + recSize(node.getRight()));
else
return (1 + recSize(node.getLeft()));
A. The code will throw a "null pointer exception" under certain circumstances.
B. The code will return an incorrect result under certain circumstances.
C. The code works correctly but could be simpler.
D. The code works correctly.
If an application uses the remove method on an Iterator object returned by our binary search tree:
A. a TreeUnderflowException is thrown.
B. an UnsupportedOperationException is thrown.
C. the application will terminate.
D. the most recently visited node of the tree will be removed.
