The most common representation of a binary tree is to use a struct or class containing a data value and two pointers, one for the left child and one for the right child. This allows for efficient traversal of the tree and easy insertion and deletion of nodes. Option A doesn't work for binary tree as it connects only to the first child, but every node usually has two or zero children. Option B only looks at the bottom level, but binary trees don't generally have a last child. Option D won't work as it will only allow two nodes, and it cannot be expanded using OOP concepts.
