I think the traversals may be incorrect. The Fact that A is first in pre order suggests it is the root node, B being second is either left of it or the first on the right where there is not left.
However The Fact that B is first on the In-order says that B is actually either root or the left most node and a child of H These two sets of conditions are mutually exclusive!
