Hydrogen A is the furthest downfield peak because of the electronegativity of the sp2 hybridized carbon to which it is attached.
Hydrogen B has a shift of 5.09 ppm.
Hydrogen C is a doublet of doublets shifted downfield due to its proximity to an oxygen atom.
Hydrogen D are a triplet of quartets also shifted downfield through the electronegativity of a close oxygen atom.
