Quizplus · Accepted Answer

The correct chair form for the anomer of D-mannose is B because the oxygen atom on the anomeric carbon is axial, which is consistent with the stereochemistry of D-mannose. In form A, the oxygen atom on the anomeric carbon is equatorial, which is not consistent with D-mannose. In form C and D, the ring is flipped, resulting in the wrong stereochemistry.
