Solution

The correct answer is 4

Explanation:

To determine the height of a binary search tree (BST) constructed with the given words (banana, peach, apple, pear, coconut, mango, and papaya) in alphabetical order, we'll insert the words into the BST one by one according to BST insertion rules.

1. Insert "banana":
               
              (Height = 0, since it's the only node and root)

2. Insert "peach":
              
              (Height = 1, right child of the root)

3. Insert "apple":
              
              (Height = 1, apple is the left child of banana)

4. Insert "pear":
             
             (Height = 2, pear is the right child of peach)

5. Insert "coconut":
             
             (Height = 2, coconut is the left child of peach)

6. Insert "mango":
             
             (Height = 3, mango is the right child of coconut)

7. Insert "papaya":
             
             (Height = 4, papaya is the right child of mango)

So, the height of the resulting binary search tree is 4, which is the number of edges from the root to the deepest leaf node.

The correct answer is: 3) 4
