(5 points) A Maximum Binary Tree (abbreviated as MaxBT) is defined as a binary tree that adheres to the max-heap property without the necessity of following the complete binary tree property. In a MaxBT, each node $p$ consists of a value ($p.\text{data}$) and two links ($p.\text{left}$ and $p.\text{right}$) pointing to the left and right children, respectively. A link to nil indicates the absence of further children.

The provided pseudocode, although incomplete, implements a recursive function for merging two MaxBTs into a single MaxBT. This function takes the root nodes of the two MaxBTs ($root1$ and $root2$) as input and returns the root node of the merged MaxBT.

1:  function MergeMaxBinaryTrees(root1, root2)
2:      if root1 = nil then return  (a)   end if
3:      if root2 = nil then return  (b)   end if
4:      if root1.data > root2.data then
5:            (c)  ← MergeMaxBinaryTrees(  (d) ,  (e) )
6:          return  (f)
7:      else
8:            (g)  ← MergeMaxBinaryTrees(  (h) ,  (i) )
9:          return  (j)
10:     end if
11: end function
