Preorder Traversal: In preorder traversal, the root node is visited first, then the left subtree is visited and then the right subtree is visited. Therefore, the sequence obtained is 5, 3, 1, 2, 4, 6, 8, 7.

Postorder Traversal: In postorder traversal, the left subtree is visited first, then the right subtree is visited and then the root node is visited. Therefore, the sequence obtained is:

1. Traverse left subtree: 2, 1
2. Traverse right subtree of 1: 4, 3
3. Visit the root node of the left subtree: 3, 4, 1, 2
4. Traverse right subtree: 7, 8
5. Visit the root node of the right subtree: 8, 7, 6
6. Visit the root node of the entire tree: 2, 1, 4, 3, 7, 8, 6, 5

Therefore, the correct answer is option 'D' (2, 1, 4, 3, 7, 8, 6, 5).
