Treating facing-centre left as clockwise. Block from clues: G-E-C-F-B consecutive clockwise (G neighbour of E, E-C-F from clue iii, F-B from clue ii). Remaining A, H, D fill the other 3 spots. H immediate left of A means A-H clockwise; H not neighbour of D forces order D-A-H-G-E-C-F-B. So D sits between B and A, making D on the immediate left of B.
