D

Energy is lost at each transfer between trophic levels (roughly ~10% passed on), so higher levels can be supported by far less biomass. The small biomass in level B is best explained by there being the fewest organisms at that level. (A is wrong because producers are at the base, B confuses individual size with total biomass, and C is false — energy flows up from producers, not from higher levels.)
